1. Do you have a scissors?

2. Do you have a pair of scissors?
3. Do you have scissors?

(Which ones are correct? Is #1 correct?)

No, # 1 is wrong. But both 2 and 3 are correct. :-)

All three sentences are grammatically correct, but they have slightly different meanings:

1. "Do you have a scissors?" - This sentence is not correct. The word "scissors" is usually used as a plural noun, so it should be "Do you have a pair of scissors?" or "Do you have scissors?" instead.

2. "Do you have a pair of scissors?" - This is the most commonly used and correct way of asking if someone has scissors. Scissors are typically sold and used in pairs, so it's more accurate to refer to them as a "pair of scissors" rather than just "scissors."

3. "Do you have scissors?" - This sentence is also correct and is a more informal way of asking if someone has scissors. It is acceptable to use the word "scissors" as a plural noun, even though it technically refers to a pair of scissors.

In summary, #2 and #3 are correct, while #1 is not.
