Identify the part of speech of the italicized word: neither john nor his sister can drive to the party.

Given that we don't know exactly which part of speech is italicized, I will just let you know what each of these words are.

Neither - a conjunction; together with nor, these are called correlative conjunctions because they denote matters of equal importance

John - a noun; a proper noun, to be more precise - they denote names

nor - like neither, it is a conjunction, used to connect parts of sentences

his - a pronoun; possessive pronoun, to be more precise, because it denotes that the sister 'belongs' to John

sister - a noun; a common noun, to be more precise

can - a verb; a modal verb, to be more precise

drive - a verb; denotes action being performed

to - a preposition; denotes place

the - an article, a definite article, to be more precise; a and an are indefinite

party - a noun; a common/abstract noun, to be more precise
