Constructive means meant to build up and improve rather than to tear down. Criticism that comes with a suggestion attached.
The phrase constructive criticism is the commonest use by far, and it promises that the fault-finding has a purpose. Constructive talks and a constructive approach both mean progress is being made. British employment law has a precise term in constructive dismissal, where an employer makes conditions so bad that the employee resigns. Its opposite is destructive, and the verb behind both is construct.
