Cohesion is the grammatical and lexical linking within a text or sentence that holds a text together and gives it meaning. It is related to the broader concept of coherence. There are two main types of cohesion: grammatical cohesion: based on structural content; lexical cohesion: based on lexical content and background knowledge.
In lexicography [citation needed], a lexical item is a single word, a part of a word, or a chain of words that forms the basic elements of a language's lexicon (≈ vocabulary). [ citation needed ] Examples are cat , traffic light , take care of , by the way , and it's raining cats and dogs .
The sequence between semantic related ordered words is classified as a lexical chain. [1] A lexical chain is a sequence of related words in writing, spanning narrow (adjacent words or sentences) or wide context window (entire text). A lexical chain is independent of the grammatical structure of the text and in effect it is a list of words that ...
Lexical choice is the subtask of Natural language generation that involves choosing the content words (nouns, non-auxiliary verbs, adjectives, and adverbs) in a generated text. Function words (determiners, for example) are usually chosen during realisation .
An extension of the sense of one word narrows the meaning of neighboring words, with the words in a field fitting neatly together like a mosaic. If a single word undergoes a semantic change, then the whole structure of the lexical field changes. The lexical field is often used in English to describe terms further with use of different words.
The lexical categories that a given grammar assumes will likely vary from this list. Certainly numerous subcategories can be acknowledged. For instance, one can view pronouns as a subtype of noun, and verbs can be divided into finite verbs and non-finite verbs (e.g. gerund, infinitive, participle, etc.).
A famous example for lexical ambiguity is the following sentence: "Wenn hinter Fliegen Fliegen fliegen, fliegen Fliegen Fliegen hinterher.", meaning "When flies fly behind flies, then flies fly in pursuit of flies." [40] [circular reference] It takes advantage of some German nouns and corresponding verbs being homonymous. While not noticeable ...
These examples demonstrate that subcategorization frames are specifications of the number and types of arguments of a word (usually a verb), and they are believed to be listed as lexical information (that is, they are thought of as part of a speaker's knowledge of the word in the vocabulary of the language). Dozens of distinct subcategorization ...
