Capable of being made smaller, reduced, or lessened in size, amount, or importance.
From Middle English 'diminishen,' derived from Old French 'diminuer,' which came from Latin 'diminuere' (di- 'away' + minuere 'to make small'). The suffix '-able' means 'capable of being.'
Everything in the physical world is technically 'diminishable,' but what's philosophically interesting is that some things—like a person's dignity or a nation's trust—people insist aren't, even though we see them shrink all the time.
