Editing Content word (section)

{{Short description|Words that supply mainly content information rather than just grammatical information}}'''Content words''', in [[linguistics]], are words that possess semantic content and contribute to the meaning of the sentence in which they occur. In a traditional approach, [[nouns]] were said to name objects and other entities, [[lexical verb|lexical verbs]] to indicate actions, [[adjectives]] to refer to attributes of entities, and [[adverbs]] to attributes of actions. They contrast with [[function words]], which have very little substantive meaning and primarily denote grammatical relationships between content words, such as [[prepositions]] (in, out, under etc.), [[pronouns]] (I, you, he, who etc.) and [[conjunction (grammar)|conjunctions]] (and, but, till, as etc.).<ref name="Sankin" />

All words can be classified as either content or function words, but it is not always easy to make the distinction. With only around 150 function words, 99.9% of words in the [[English language]] are content words. Although small in number, function words are used at a disproportionately higher rate than content and make up about 50% of any English text because of the conventional patterns of usage that binds function words to content words almost every time they are used, which creates an interdependence between the two word groups.<ref name=Sankin>{{citation|title=A Course in Modern English Lexicology|edition=Revised and Enlarged, Second|first=A.A.|last=Sankin|editor=R.S.

Content words are usually [[open class (linguistics)|open class]] words, and new words are easily added to the language.<ref>{{Cite book|last=Winkler|first=Elizabeth Grace|title=Understanding Language|publisher=Continuum|year=2007|isbn=978-08264-84833|pages=84–85}}</ref> In relation to [[English phonology]], content words generally adhere to the minimal word constraint of being no shorter than two [[mora (linguistics)|morae]] long (a minimum length of two light syllables or one heavy syllable), but function words often do not.<ref>{{cite web|title=Function Words|first=Liina|last=Pylkkanen|website=NYU Department of Psychology|url=http://www.psych.nyu.edu/pylkkanen/Neural_Bases/13_Function_Words.pdf|access-date=December 18, 2016|archive-date=August 30, 2017|archive-url=https://web.archive.org/web/20170830014227/http://www.psych.nyu.edu/pylkkanen/Neural_Bases/13_Function_Words.pdf|url-status=dead}}</ref>
