an answer & a new riddle

Thank you everyone for guessing on my riddle post the last few days. It's about time that I revealed the correct answer! For a quick update, this was the riddle:

"I know a word of letters three. Add two and fewer there will be."

...and the answer to this excellent riddle is.... the word: Few    :~D


I feel like I'm on a roll here, and I don't want to mess up the momentum of throwing these riddles at you. So, I have a new one!!
Here it is:

What English word has 3 consecutive double letters?

{This is a pretty tough one... So think hard about all the words you know. And I don't mind if you use some "help".}
