Did You Know?

Appreciable, like the verb "appreciate," comes from the Late Latin verb appretiare ("to appraise" or "to put a price on"). It is one of several English adjectives that can be applied to something that can be detected, felt, or measured. Specifically, "appreciable" applies to what is highly noticeable or definitely measurable, whereas "perceptible," which is often paired with "barely" or "scarcely," applies to what can be discerned to a minimal extent. "Sensible" refers to something that is clearly perceived; a sensible difference in someone's expression is easily detected. "Palpable" applies to something that, if it doesn't have actual physical substance, is nevertheless quite noticeable via the senses ("a palpable chill in the air"). "Tangible" is used for something capable of being handled or grasped, either physically or mentally ("tangible evidence").
