, and definition. Lexicology also considers the relationships that exist between words. In linguistics, the lexicon of a language is composed of lexemes, which are abstract units of meaning that correspond to a set of related forms of a word. Lexicology looks at how words can be broken down as well as identifies common patterns they follow. Lexicology is associated with lexicography, which is the practice of compiling dictionaries.

Etymology

The term ''lexicology'' derives from the Greek word λεξικόν ''lexicon'' (neuter of λεξικός ''lexikos'', "of or for words", from λέξις ''lexis'', "speech" or "word") and -λογία ''-logia'', "the study of" (a

suffix In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns, adjectives, and verb endings, which form the conjugation of verbs. Suffixes can carr ...

'', amongst others meaning "learning, reasoning, explanation, subject-matter"). Etymology as a science is actually a focus of lexicology. Since lexicology studies the meaning of words and their semantic relations, it often explores the history and development of a word. Etymologists analyze related languages using the comparative method, which is a set of techniques that allow linguists to recover the ancestral phonological, morphological, syntactic, etc., components of modern languages by comparing their cognate material. This means many word roots from different branches of the Indo-European language family can be traced back to single words from the

Approach

General lexicology is the broad study of words regardless of a language's specific properties. It is concerned with linguistic features that are common among all languages, such as phonemes and morphemes. Special lexicology, on the other hand, looks at what a particular language contributes to its vocabulary, such as

grammars In linguistics, the grammar of a natural language is its set of structural constraints on speakers' or writers' composition of clauses, phrases, and words. The term can also refer to the study of such constraints, a field that includes doma ...

. Altogether lexicological studies can be approached two ways: # Diachronic or historical lexicology is devoted to the evolution of words and

word-formation In linguistics, word formation is an ambiguous term that can refer to either: * the processes through which words can change (i.e. morphology), or * the creation of new lexemes in a particular language Morphological A common method of word form ...

over time. It investigates the origins of a word and the ways in which its structure, meaning, and usage have since changed. # Synchronic or descriptive lexicology examines the words of a language within a certain time frame. This could be a period during the language's early stages of development, its current state, or any given interval in between. These complementary perspectives were proposed by Swiss linguist Ferdinand de Saussure. Lexicology can have both comparative and contrastive methodologies. Comparative lexicology searches for similar features that are shared among two or more languages. Contrastive lexicology identifies the linguistic characteristics which distinguish between related and unrelated languages.

Semantics

The subfield of semantics that pertains especially to lexicological work is called lexical semantics. In brief, lexical semantics contemplates the significance of words and their meanings through several lenses, including synonymy,

antonymy In lexical semantics, opposites are words lying in an inherently incompatible binary relationship. For example, something that is ''long'' entails that it is not ''short''. It is referred to as a 'binary' relationship because there are two members ...

and onomasiology are relevant linguistic disciplines associated with lexical semantics. A word can have two kinds of meaning: grammatical and lexical. Grammatical meaning refers to a word's function in a language, such as tense or plurality, which can be deduced from

affixes In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. Affixes may be derivational, like English ''-ness'' and ''pre-'', or inflectional, like English plural ''-s'' and past tense ''-ed''. They ar ...

. Lexical meaning is not limited to a single form of a word, but rather what the word denotes as a base word. For example, the

verb A verb () is a word ( part of speech) that in syntax generally conveys an action (''bring'', ''read'', ''walk'', ''run'', ''learn''), an occurrence (''happen'', ''become''), or a state of being (''be'', ''exist'', ''stand''). In the usual descr ...

''to walk'' can become ''walks'', ''walked'', and ''walking –'' each word has a different grammatical meaning, but the same lexical meaning ("to move one's feet at a regular pace").

Phraseology

Another focus of lexicology is phraseology, which studies multi-word expressions, or idioms, like 'raining cats and dogs.' The meaning of the phrase as a whole has a different meaning than each word does on its own and is often unpredictable when considering its components individually. Phraseology examines how and why such meanings exist, and analyzes the laws that govern these word combinations. Idioms and other phraseological units can be classified according to content and/ or meaning. They are difficult to translate word-for-word from one language to another.
