Characteristics
Cognates need not have the same meaning, as they may have undergone
semantic change as the languages developed independently. For example

Dutch ''
sterven'' 'to die' or
German ''
sterben'' 'to die' all descend from the same

Paradigms of conjugations or declensions, the correspondence of which cannot be generally due to chance, have often been used in cognacy assessment. However, beyond paradigms, morphosyntax is often excluded in the assessment of cognacy between words, mainly because structures are usually seen as more subject to borrowing. Still, very complex, non-trivial morphosyntactic structures can rarely take precedence over phonetic shapes to indicate cognates. For instance,

, Geshiza, both display a verbal alternation indicating tense, obeying the same morphosyntactic collocational restrictions. Even without regular phonetic correspondences between the stems of the two languages, the cognatic structures indicate secondary cognacy for the stems.
False cognates
False cognates are pairs of words that appear to have a common origin, but which in fact do not. For example, Latin and German both mean 'to have' and are phonetically similar. However, the words evolved from different

(PIE) roots: , like English ''have'', comes from PIE ''
*kh₂pyé-'' 'to grasp', and has the Latin cognate ''capere'' 'to seize, grasp, capture'. , on the other hand, is from PIE ''*gʰabʰ'' 'to give, to receive', and hence cognate with English ''give'' and German .
Likewise, English ''much'' and Spanish look similar and have a similar meaning, but are not cognates: ''much'' is from Proto-Germanic ''
*mikilaz'' < PIE ''
*meǵ-'' and is from Latin ''multum'' < PIE ''
*mel-''. A true cognate of ''much'' is the archaic Spanish 'big'.
Distinctions
Cognates are distinguished from other kinds of relationships.
*
Loanword
A loanword (also a loan word, loan-word) is a word at least partly assimilated from one language (the donor language) into another language (the recipient or target language), through the process of borrowing. Borrowing is a metaphorical term t ...
s are words borrowed from one language into another; for example, English ''beef'' is borrowed from Old French ''boef'' (meaning "ox"). Although they are part of a single etymological stemma, they are not cognates.
*
Doublets are pairs of words in the same language which are derived from a single etymon, which may have similar but distinct meanings and uses. Often, one is a loanword and the other is the native form, or they have developed in different dialects and then found themselves together in a modern standard language. For example, Old French ''boef'' is cognate with English ''cow'', so English ''cow'' and ''beef'' are doublets.
*
Translation
Translation is the communication of the semantics, meaning of a #Source and target languages, source-language text by means of an Dynamic and formal equivalence, equivalent #Source and target languages, target-language text. The English la ...
s, or semantic equivalents, are words in two different languages that have similar or practically identical meanings. They may be cognate, but usually they are not. For example, the German equivalent of the English word ''cow'' is ''Kuh'', which is also cognate, but the French equivalent is ''vache'', which is unrelated.
Related terms
Etymon (ancestor word) and descendant words
An
etymon, or ancestor word, is the ultimate source word from which one or more cognates derive.
In other words, it is the source of related words in different languages.
For example, the etymon of both Welsh ''ceffyl'' and Irish ''capall'' is the Proto-Celtic *''kaballos'' (all meaning ''horse'').
Descendants are words inherited across a language barrier, coming from a particular etymon in an ancestor language.
For example, Russian ''мо́ре'' and Polish ''morze'' are both descendants of Proto-Slavic *''moře'' (meaning ''sea'').

is the source of related words within a single language (no language barrier is crossed).
Similar to the distinction between ''etymon'' and ''root'', a nuanced distinction can sometimes be made between a ''descendant'' and a ''derivative''.
A
derivative
In mathematics, the derivative is a fundamental tool that quantifies the sensitivity to change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is t ...
is one of the words which have their source in a root word, and were at some time created from the root word using morphological constructs such as suffixes, prefixes, and slight changes to the vowels or to the consonants of the root word.
For example ''unhappy'', ''happily'', and ''unhappily'' are all derivatives of the root word ''happy''.
The terms ''root'' and ''derivative'' are used in the analysis of morphological derivation within a language in studies that are not concerned with historical linguistics and that do not cross the language barrier.
