go-ahead

The compound "go-ahead" is a transparent phrasal verb turned noun and adjective, formed entirely from native English elements. The verb "go," with Proto-Germanic origins meaning to walk or move, combines with "ahead," which literally meant "at the head" or "in front." The literal sense of "proceed forward" evolved in the 19th century into the figurative meaning of granting permission to proceed, as in giving someone the signal to "go ahead." This later nominalized to mean the permission itself and adjectivized to describe a person or attitude characterized by initiative and a willingness to move forward with new ideas.

Structure: go (move, proceed) + ahead (in front, forward) - go: From Old English 'gān', meaning to move, proceed, or travel.
