Part of Speech - Controversies

Controversies

Since the Greek grammar of 2nd century BCE, parts of speech have been defined by morphological, syntactic and semantic criteria. However, there is currently no generally agreed-upon classification scheme that can apply to all languages, or even a set of criteria upon which such a scheme should be based.

Linguists recognize that the above list of eight word classes is drastically simplified and artificial. For example, "adverb" is to some extent a catch-all class that includes words with many different functions. Some have even argued that the most basic of category distinctions, that of nouns and verbs, is unfounded, or not applicable to certain languages.
