Sure is an adjective. :)
Noun--however, many words have several possible parts of speech; please submit the Whole Sentence when asking for part of speech--cannot be sure without seeing how it is used in the sentence, as that's what determines the part of speech.
This is called a particle or sometimes an interjection.
Pretty sure its the direct Object.
In the sentence, "My back hurts," it is a noun. In the sentence, "Bring it back down here," I think it is an adverb, but I'm not sure.
Bias is a noun in that sentence.
Not sure if it is preposition or adverb. What does it modify?
Which to? The first to is a preposition. The last to is an adverb. (Are you sure that you didnt mean too?) Or to with an object?)
i think this is the answer for sure :noun
preposition for sure
i think it is a prepositional phrase but i am not 100% sure
im not sure
