@galatasaraylikiz22,
Quote:Which parts of speech would you assign to the following examples ???
a) three
b) second
c ) oh
d) aha
Parts of speech rarely can be described in isolation. Other than 'aha', [and there might be a situation I'm missing even for this one], the other three would have to appear in a sentence to know for certain what part of speech they are.
'oh' is an interjection and a noun, the latter when it means 'zero'.
