Match the Verb to the Kind of Reduction

Reduce is flexible, while curtail usually implies deliberate limitation, shrink and contract emphasize scale, and deplete focuses on exhausting a resource. Subtract is mathematical rather than a general stylistic replacement.

Reduction verbs also differ in agency. Decrease and shrink can describe changes that happen on their own, while cut, trim and curtail usually suggest deliberate action. That difference can change who appears responsible for the reduction.
