open-class word
Noun: A word belonging to a category that readily accepts new members; a word to which an independent meaning can be assigned. Open-class words are the content words of a language (e.g., nouns, verbs, adjectives, adverbs) as opposed to closed-class words (e.g., prepositions, conjunctions, articles), which are function words.
This term is used in linguistics to categorize and analyze vocabulary. It describes words that carry the primary semantic content in a sentence and whose categories are productive, meaning new words can be easily created and added to them. - In English, nouns, verbs, adjectives, and most adverbs are considered open-class words. - The constant addition of new technology terms like "blog" or "selfie" demonstrates that nouns are an open-class word category.
- Contrast with 'Closed-Class Word': The concept is primarily defined in opposition to closed-class words (or function words). Open-class words have lexical meaning, while closed-class words have grammatical meaning.
- The sentence "The quick brown fox jumps" contains only open-class words, whereas "over the lazy dog" introduces closed-class words ("over", "the").
