7 letter word beginning with ab?

Answer 1

A quick look in the dictionary will show you "all" of them - 'all' being defined according to the size of the dictionary. If the "ab" is a prefix then it means "away from" as in 'abnormal' 'abdicate" 'abstain' 'abhor' and (perhaps) even 'ab-use' (away from using, abusing instead.) ALSO in many words that begin with just "a" the 'a' still means "away from" and the "b" is omitted for ease of pronunciation: For example: amoral (easier to say than "abmoral"), agnostic, atypical, asocial.

Answer 2

abstain
