助词, 副词性成分
(grammar) an adverb or preposition that is used with a verb to form a phrasal verb
In linguistics, a particle is a small word that does not change form and is used to express a grammatical function rather than a specific meaning. Particles can help modify or clarify the role of other words in a sentence. In English, examples of particles include words like "to" in "to go" or "not" in "do not." Particles do not fit easily into other word categories like nouns, verbs, or adjectives, and they usually provide grammatical context, helping to form phrases, indicate negation, or show relationships between words.
