Root Breakdown
Root-derivedfract (break) + -ion (act/result) = 'a broken-off part.' Break a whole and each piece is a fraction. Mathematics made it exact — a piece of a whole written as one number over another — but everyday English kept the loose sense: a fraction of the cost, a fraction of a second.
