Origin
From Old English calu (bald, bare); later used of unfledged birds and then of inexperienced youth.
History
Callow once described bare ground and young birds without feathers. The transfer to naive young people followed a clear image: not yet ready for flight. Critics still use it for early work that shows promise without judgment. It stings less than foolish when the fault is simply lack of years.
