corrigible

Corrigible describes someone or something that can be corrected, reformed, or improved.

It applies most often to behavior or character that is amenable to discipline or guidance: The young offender seemed corrigible, responding well to the rehabilitation program.

The word is considerably rarer than its opposite, incorrigible, which describes someone beyond correction or reform.

In technical contexts, particularly artificial intelligence, corrigible refers to systems designed to accept correction or modification by their operators.
