Why “underprize” is a great word
UNDERPRIZE — [Verb] To value or esteem something at less than its true worth. Formed within English by derivation from the prefix under- (denoting insufficiency or lower position) and the verb prize (meaning to value or esteem). Unlike "undervalue," which often implies a fiscal or market calculus, or "underestimate," which concerns an error in judging magnitude or likelihood, to underprize denotes a specific failure to appreciate inherent merit—a quiet failure of recognition. It is the collector overlooking the humble sketch for the showy frame, the gardener discarding the unassuming tuber while tending the flashy blooms, the society venerating the loud opinion and failing to hear the quiet wisdom in the corner. We are forever misplacing our deepest prizes, letting familiarity render the priceless invisible.
Etymology
From under- + prize.
verb
- To undervalue; to underestimate.“[…] Yet look, how far / The substance of my praise doth wrong this shadow / In underprizing it, so far this shadow / Doth limp behind the substance.”
