i don't know the italicized word an adjective discribes something a noun is a person place or thing a pronoun is in place of a noun (he, she, it) and an adverb modifies an adjective, verb, or other adverb
Since you didn't italicize anything, I will just write every part of speech. 'Large' - adjective. 'Fish' - noun. 'Swim' - verb. 'In' - preposition. 'The' - determiner. 'Sea' - noun.
