Question

In the following sentence, identify the part of speech of the italicized word. Large fish swim swiftly in the sea.

Answer 1

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

Answer 2

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.
