The distinction between "endocentric" digraphs and empty letters is somewhat
arbitrary. For example, in such words as ''little'' and ''bottle'', one might view as an "endocentric" digraph for , or view as an empty letter; similarly, with or in ''buy'' and ''build''.
Not all silent letters are completely redundant:

homophones; e.g., ''in''/''inn''; ''be''/''bee''; ''lent''/''leant''. This is an aid to readers already familiar with both words.

Differences between British English and American English
Pronunciation
In the US, the ''h'' in ''herb'' is silent (''an herb''), but in the UK, it is pronounced (''a herb''). The same is true for the ''l'' in ''solder.''
In parts of the UK, the ''a'' in ''dictionary'' and ''secretary'' is silent, but in the US, it is pronounced.
Spelling
In US spellings, silent letters are sometimes omitted (e.g., ''acknowledgment'' / UK ''acknowledgement'', ''ax'' / UK ''axe'', ''catalog'' / UK ''catalogue'', ''program'' / UK ''programme'' outside computer contexts), but not always (e.g., ''dialogue'' is the standard spelling in the US and the UK; ''dialog'' is regarded as a US variant; the spelling ''axe'' is also often used in the US). In most words, silent letters are written in both styles (e.g., ''debt'', ''guard'', ''house'').
Other Germanic languages
Danish
The Danish language has different letters that can be silent:
* The letter is silent in the preposition ''af'' ('by, of, from, off, with, out of').
* The letter is silent in the conjunction ''og'' ('and') and adverb ''også'' ('also').
* The letter is silent in most dialects if followed by , as in the pronouns ''hvad'' ('what'), ''hvem'' ('who'), ''hvor'' ('where').
* The letter is silent at the end of words if preceded by , as in the pronoun ''selv'' ('self') and adjective ''halv'' ('half').
* The letter is usually (but not necessarily) silent if preceded by a consonant, as in ''en mand'' ('a man') and ''blind'' ('blind'). Many words ending in are pronounced with a
stød, but it is still considered a silent letter.

Both Faroese silent letters and are replaced by a
hiatus glide consonant (, or ) when followed by another (unstressed) vowel.
German
In German, silent letters are rare apart from word-internal (following a vowel) and the in the
digraph .
Silent ''h'' is used in German to indicate vowel length or
hiatus. This ''h'' is almost regularly added at the end of
inflectable word stems, e.g. ''Kuh'' (cow), ''Stroh'' (straw), ''drehen'' (to turn, stem ''dreh''-). There is only a fairly small number of exceptions to this, mostly nouns in ''-ee'' or ''-ie'' (see below), apart from isolated cases such as ''säen'' (to sow).
Otherwise silent ''h'' may be written before the letters ''l, m, n, r'' as in ''nehmen'' (to take), ''Stuhl'' (chair), ''Zahn'' (tooth). This latter use is highly irregular, however, and there are just as many words where the ''h'' is missing.
Historically, this use of silent ''h'' goes back to the
Middle High German
Middle High German (MHG; or ; , shortened as ''Mhdt.'' or ''Mhd.'') is the term for the form of High German, High German language, German spoken in the High Middle Ages. It is conventionally dated between 1050 and 1350, developing from Old High ...
consonant , which became silent in words like ''sehen'' (to see), ''zehn'' (ten). By analogy it was then also used in words that had no such ''h'' in Middle High German. The majority of silent ''h'' in modern German are analogical rather than etymological.
The long ''i''-sound is usually written , with a silent , as in ''viel'' (much), ''spielen'' (to play), ''Wien'' ('

'), and hundreds of other words.
In native German words this spelling is fairly unambiguous. Some words of foreign origin also behave like native words; e.g., ''Kurier, Papier, Turnier'' and all verbs ending in (e.g. ''appellieren, organisieren''). In other foreign words, however, the after may be pronounced (e.g., ''Ambiente'', ''Hygiene'', ''Klient''), or names like ''Daniela'', ''Gabriel'', and ''Triest''.
Words ending in can be particularly tricky to learners: There are generally two possibilities:
# When the final is stressed, it represents long as in ''Zeremonie'' . Some other words with pronounced this way include ''Akademie'', ''Allergie'', ''Amnesie'', ''Amnestie'', ''Apathie'', ''Artillerie'', ''Batterie'', ''Blasphemie'', ''Chemie'', ''Chirurgie'', ''Demokratie'', ''Energie'', ''Epidemie'', ''-gamie'', ''Garantie'', ''Genie'', ''Geometrie'', ''-grafie/-graphie'', ''Harmonie'', ''Hysterie'', ''Infanterie'', ''Ironie'', ''Kavallerie'', ''Kompanie'', ''Kopie'', ''
-logie'', ''Liturgie'', ''Magie'', ''Manie'', ''Marie'', ''Melodie'', ''Monotonie'', ''Nostalgie'', ''Orthopädie'', ''Partie'', ''Phantasie'', ''Philosophie'', ''Poesie'', ''Psychiatrie'', ''Rhapsodie'', ''Sinfonie'', ''-skopie'', ''Theorie'', ''Therapie'', and ''Utopie''.
# When the preceding vowel is stressed, represents the separate vowels as in ''Folie'' . Some other words with pronounced this way include ''Akazie'', ''Aktie'', ''Amalie'', ''Begonie'', ''Emilie'', ''Familie'', ''Folie'', ''Geranie'', ''Grazie'', ''Hortensie'', ''Hostie'', ''Immobilie'', ''Kastanie'', ''Komödie'', ''Kurie'', ''Lilie'', ''Linie'', ''Orgie'', ''Otilie'', ''Pinie'', ''Serie'', ''Studie'', ''Tragödie'', and ''Zäzilie''.
# In female names, there is a third category of words stressed on the
antepenult, where also represents ; e.g., ''Amelie'', ''Leonie'', ''Nathalie'', ''Rosalie'', ''Stefanie'', ''Valerie'' (all stressed on the first syllable).
A special case arises when the after is a grammatical ending; in this case, it is always pronounced. Therefore, ''Zeremonie'' becomes ''Zeremonien'' in the plural, and the same is true of all other nouns in group 1 above. The noun ''Knie'' is pronounced when it is singular, but usually when it is plural. ''Spermien'' is plural of ''Spermium'', hence also with a pronounced . Country names in ''-ien'' can also be joined to this group: ''Australien'', ''Brasilien'', ''Indien'', ''Kroatien'', ''Serbien'', ''Slowenien''.
Other letters
Other silent letters occur mainly in borrowings from
French and other modern languages; e.g., ''Porträt'' (portrait), ''Korps'' (corps).
Informally, the letter may be silent in
function words like ''ist'' (is), ''jetzt'' (now), ''nicht'' (not), and otherwise in clusters like ''Gedächtnis'' (memory), ''Kunststück'' (piece of art). These ''t'' are commonly silent in everyday speech, but will be retained in careful, formal parlance.
Romance languages
French
Silent letters are common in
French, including the last letter of most words. Ignoring auxiliary letters that create digraphs (such as , , , , , , and , as well as and as signals for
nasalized vowels), they include almost every possible letter except and .
Vowels
Final is silent or at least (in poetry and song) a nearly-silent
schwa ; it allows the preservation of a preceding consonant, often allowing the preservation of a grammatical distinction between
masculine and feminine forms in writing; e.g., in ''vert'' and ''verte'' (both 'green'); the is pronounced in the latter (feminine) but not the former. Furthermore, the schwa can prevent an awkward ending of a word ending in a consonant and a liquid (''peuple, sucre'').
After , , or , a final is silent. The spelling is pronounced just the same as that for and is entirely an etymological distinction, so in that context, the is silent.
The digraph for usually has a silent , as in ''quand'' ('when'), ''quel'' ('which'), ''acquérir'' ('to acquire'), and ''quotidien'' ('daily'). for has the same silent ; when the is not silent, it is usually marked with a
trema: .
Consonants

Italian does. A marked distinction exists between a single and doubled : doubled is always

The nasal consonants and when final or preceding a consonant ordinarily nasalize a preceding vowel but are not themselves pronounced (''faim'', ''tomber'', ''vin'', ''vendre''). Initial and intervocalic and , even before a final silent , are pronounced: ''aimer'', ''jaune''.
Most final consonants are silent, except in most cases with the letters , , , and (the English word ''careful'' is a

Final and is silent after even in a diphthong (''œil'', ''appareil'', ''travail'', ''bouillir''). Final -''ent'' is silent as a third-person plural verb ending, though it is pronounced in other cases.
Final consonants that might be silent in other contexts (finally or before another consonant) may seem to reappear in pronunciation in
liaison: ''ils ont'' "they have", as opposed to ''ils sont'' "they are"; liaison is the retention (between words in certain syntactic relationships) of a
historical sound otherwise lost, and often has grammatical or lexical significance.

Despite being rather

Spanish orthography retains some silent letters:

* The digraph , used to represent before the front vowels and , has a silent . In contrast, the u is pronounced in .
* for has the same silent before and . When the is not silent, it must be marked with a

* Syllable onsets like , , are usually pronounced without ''p''. In some but not all cases, this is reflected in the orthography that allows double forms with and without : ("tire"), / ("psychology"), / ("
pterodactyl"). Reducing an internal ( instead of , "concept") is not recommended except in ("September") and / ("seventh").
* An internal may be pronounced with a silent . In some cases, this is considered vulgar; in others, it is the most common pronunciation and reflected in the orthography: ("substance").

In the vast majority of cases, Czech pronunciation follows the spelling. There are only four exceptions:

For example: dcera (daughter) and in srdce (heart)
/j/ + consonant clusters in some words
In most present forms of the verb ''být'' ("to be"), namely ''jsem'', ''jsi'', ''jsme'', ''jste'' and ''jsou'' (i.e., all persons but the third-person singular ''je''), the initial cluster /js/ is regularly simplified to a mere /s/. This pronunciation is considered correct and neutral when the verb is unstressed and used as an auxiliary. When stressed or used lexically, only the full /js/ pronunciation is considered correct. In casual speech, however, a few other highly frequent words commonly undergo similar simplification, namely all present forms of ''jít ''("to walk") beginning with /jd/ (that is ''jdu'', ''jdeš'', ''jde'', ''jdeme'', ''jdete'', ''jdou''), and the noun ''jméno'' ("name") (as well as the derived verb ''jmenovat (se)'' 'to name, to (''be'') call(''ed'')').

* The Hebrew word for "no" is (sounds like "lo", spelled like "loa") and the Arabic word for "no" is (sounds and spelled like "laa").
* The Hebrew word for "left side" is (sounds like "smol", spelled like "smoal") and an Arabic word for "left side" is (sounds and spelled like "shimaal").
* The Hebrew word for "head" is (sounds like "rosh", spelled like "roash") and the Arabic word for "head" is (sounds and spelled like "ra's").
The explanation for this phenomenon is that the Hebrew language had a
sound change of all the mater lectionis aleph letters into silent ones (see
Canaanite shift). Due to that sound change, in Hebrew language, there are only two kinds of aleph - the

The silent Arabic alif is marked with a
wasla sign above it (see picture), in order to differentiate it from the other kinds of alifs. An Arabic alif turns silent, if it fulfills three conditions: it must be in a beginning of a word, the word must not be the first one of the sentence, and the word must belong to one of the following groups:

Some of these words have a Hebrew word equivalent, and that equivalent had totally lost the beginning aleph. Examples: (ʔism), meaning "a name" (in Maltese the word ''isem''), sounds like "ism" if it is in the beginning of the sentence and "sm" if not; its Hebrew equivalent is (shem). (ʔibn) (in Maltese, the word ''iben''), meaning "a son", sounds like "ibn" if it is in the beginning of the sentence and "bn" if not; its Hebrew equivalent is (ben), in Maltese ''bin''.

Tamil
Tamil is a classical language phonetically characterized by
allophones,
approximants,
nasals and
glottalised sounds. Some words, however, have silent letters in them. The words அஃது (while that is), and அஃதன் (that) contain the ''
Āytam'' or '', which is not pronounced in Modern Tamil. It is explained in the ''Tolkāppiyam'' that ''āytam'' could have
glottalised the sounds it was combined with, though some may argue it sounded more like the Arabic '' (). That being said, modern words like ஆஃபிஸ் (Office) use '' and '' in sequence to represent the sound, as the ''āytam'' is nowadays also used to transcribe it and other foreign phonemes.
Another convention in

s from
Tamil, in Malayalam, except for Sanskrit words, words ending in the vowel '' () become silent at the end and if not compounded with words succeeding them, replace the '' vowel by the schwa . However, it is considered disrespectful to change this pronunciation in the simple present verbs, when using imperatives and using what can be termed as Imperative-Active voice in Malayalam, where the second person is respectfully addressed with his or her name instead of നീ (, you) or നിങ്ങൽ (, yourselves). For example, in the sentence, രാകേശ് പണി തീർക്കു (, Rakesh, finish your work), the use of the second personal pronoun is avoided with the name രാകേശ് (, Rakesh), but this sentence sounds less respectful if the '' in തീർക്കു (, finish} is replaced by the schwa or , as in "തീർക്കു!" (, Finish!) which sounds like an order. Notice the at the end of the name Rakesh which is pronounced after being added to the Sanskritic name.
Bengali
Unlike other Indic languages, Bengali features silent consonants, which occur in many consonant clusters. These silent letters usually occur in loanwords borrowed from Sanskrit. These silent letters occur due to sound mergers as the spellings of Sanskrit loanwords have been preserved but their pronunciation has changed with sound mergers.
The letter ব ('b') is silent in most of the consonant clusters where it occurs as the second one. For example, স্বপ্ন (স্ব = স্ 'sh' + ব) (dream) is written as "shbôpno" but pronounced as "shôpno".
জ্বর (জ্ব = জ্ 'j' + ব) (fever) is written as "jbôr" but pronounced as "jôr". This is the case with consonant clusters at the beginning of the words.
If the consonant cluster occurs in the middle or at the end of a word, the ব serves as a marker to put stress on the first consonant in a consonant cluster. For example, বিশ্বাস (শ্ব = শ্ 'sh' + ব) (to believe) is written as " bishbāsh" but pronounced as " bishāsh" with more stress on the sh than usual, which sounds like "bishshāsh".
The letter ম ('m') also remains silent in many initial consonant clusters. For example, "স্মৃতি" (স্মৃ = স্ 's' + ম + ঋ 'ri') (memory) is written as "smriti" but pronounced as "sriti". In many cases, if the consonant cluster occurs in the middle of a word, then the preceding vowel should be nasalised and the first letter in the cluster is stressed and ম in the cluster is silent. For example, আত্মা (ত্মা = ত্ 't' + মা 'mā'), i.e., "ātmā" (soul), is pronounced as "''ā''ttā" and the ''ā'' is nasalised.
The letter য় ('y') is also silent in many cases as in "মেয়ে" (য়ে = য় + এ 'ē') (girl) is written as "mēyē" but pronounced as "mē".
The letter 'য' ('j') in its consonant clusters changes the pronunciation of the other letters in the cluster. For example, ন্যায় (ন্যা = ন 'n'+ য + আ 'ā') (justice) is written as "njāy" but pronounced as "nay" (a as in hat); কন্যা (girl or daughter) is written as "konjā" but pronounced as "konnā". Sometimes it is completely silent as in সন্ধ্যা (ন্ধ্যা = ন্ 'n' + ধ 'dh' + য + আ 'ā') (evening) is written as "shondhjā" but pronounced as "shondhā".
Moreover, Bengali also features schwa deletion common to other Indo-Aryan languages, where the schwa, 'o' or 'ô' is omitted while pronunciation, for example, কাকতলা (incident) is written as "kākotôlā" but pronounced as "kāktôlā".
Similarly, in many other consonant clusters, the second consonant is silent.

, and rather than spell aforementioned words according to Thai phonics, the script tends to maintain the etymological spellings. For example, a romanization of the word ประโยชน์ that reflects Thai orthography is , but it would be pronounced as , where the extra letter for ''-n'' is completely silent. Another example is the Thai word มนตร์, which is sometimes written as ''mantra'' like it would be in Sanskrit, but it is only pronounced in Thai. Though the second syllable is pronounced in Sanskrit, it is completely absent when pronouncing the word in Thai. In such words, the diacritic , known as (), is used to mark silent letters.
Also, different letters can be used for the same sound (for example,
ʰcan be spelled as , , , , , or ) depending on which class the consonant is, which is important for knowing which tone the syllable will have, and whether or not it is a loanword from Sanskrit or Pali. However, some letters written before low class consonants become silent and turn the low class syllable into a high class one. For example, even though the high class letter is used to write the sound /h/, if the letter comes before a low class letter in a syllable, the letter will become , which will make the letter silent and it will turn the syllable into a high class syllable. For example, the word is a low class syllable because its initial consonant is a low class consonant. The syllable is pronounced (with a long vowel and mid tone) and it means "field". However, the word is a high class syllable, despite it containing a low class consonant in the
onset. The syllable is pronounced (with a long vowel and a rising tone) and it means "thick".
Lao
Like Thai,
Lao also has a letter that becomes silent if it comes before a low class consonant. The letter is ''ho sung'' ຫ, which would represent the sound /h/ if it were not paired with another low class consonant. However, unlike Thai, the digraphs beginning with the aforementioned letter can sometimes be written as a
ligature.

, the letter ⟨ㅇ⟩ is silent when written in the syllable-initial position, and represents the sound /ŋ/ when written in the syllable-final position. For example, in the word 안녕 (
Yale Romanization: ) (meaning "hello"), composed of the letters "ㅇㅏㄴㄴㅕㅇ", the first ⟨ㅇ⟩ is silent, and the last ⟨ㅇ⟩ is pronounced as /ŋ/. The reason for this can be found in 15th-century Hangul orthography. In the 15th century, the letter ⟨ㅇ⟩ originally represented /∅~ɣ/ (a
lenited form of ㄱ /k/), while the letter ⟨ㆁ⟩ unconditionally represented /ŋ/. But because in Middle Korean phonology, ⟨ㆁ⟩ was not allowed in syllable-initial position, and ⟨ㅇ⟩ was not allowed in syllable-final position, it formed a complementary distribution of the two letters. Because of this and due to the fact that the letters look very much alike, the two letters merged.
Korean's syllable structure is CGVC, and Korean's writing system,

, reflects this structure. The only possible consonant cluster in a single syllable must contain a
glide and they must occur in the
onset. However, sometimes a cluster of two consonants are written after the vowel in a syllable. In such situations, if the next syllable begins with a vowel sound, then the second consonant becomes the first sound of the next syllable. However, if the next syllable begins with a consonant sound, then one of the consonants in the cluster will be silent (sometimes causing
fortition in the following consonant). For example, the word 얇다 (meaning "thin") is written as (
Yale: ''yalp.ta''), but the word is pronounced as if it was written ''yal.tta'' because the second syllable begins with a consonant sound. However, the word 얇아서 (also meaning "thin") is written as (
Yale: ''yalp.a.se'') and it is pronounced as ''yal.pa.se'' because the second syllable begins with a vowel sound.

orthographic depth than

In that case, the silent consonant letter combines to two written vowel into one long vowel. For example, the Mongolian word ''Qaγan'' (ᠬᠠᠭᠠᠨ) should be pronounced ''Qaan'' (ᠬᠠᠠᠨ). In Mongolian Cyrillic, however, it is spelled ''хаан'' (''haan''), closer to the actual pronunciation of the word. Words in the Mongolian script can also have silent vowels as well.

During the standardization of Basque in the 1970s, the compromise was reached that would be accepted if it were the first consonant in a syllable. Hence, ("people") and ("to come") were accepted instead of (
Biscayan) and (
Souletin). Speakers could pronounce the h or not. For the dialects lacking the aspiration, this meant a complication added to the standardized spelling.
