closed word class
/ˈkloʊzd wɜːrd klæs/A grammatical category of words that has a fixed, limited set of members and does not readily accept new words.
Pronouns such as 'he', 'she', and 'it' are part of the closed word class in English.
These words cannot be easily replaced with new forms.
Prepositions like 'in', 'on', and 'at' form a closed word class.
The list of prepositions is relatively stable over time.
Closed word classes contrast with open word classes (e.g., nouns, verbs), which can expand with new words.
