nountagged
nountagged is a term used in linguistic analysis and computational linguistics to refer to a word that has not been assigned a grammatical tag. This tag, often called a part-of-speech (POS) tag, identifies the grammatical category of a word, such as noun, verb, adjective, or adverb. Nountagged words are therefore words whose grammatical function within a sentence or text is unknown or unassigned by a particular system or process.
In natural language processing (NLP), the process of assigning POS tags to words is known as POS
For instance, a word like "run" can be a verb ("I run every day") or a noun
