This is my first question here.
I am not a fluent English speaker. I just know the basics.
My question is how many m‘s should be there in “hmm” as when I try typing it anywhere, it suggests “hmmm,” even on SO sites, including this one.
Is there is any reason for this ?
Hmm. The Macmillan Dictionary has a listing for hmm, but not for hm or hmmm.
