Did you know?

If you assumed that appreciable means “able to be appreciated,” we see you and we appreciate you. You’ve got a good eye for word families: appreciable does indeed share an ancestor with appreciate. However, the former does not describe things that are worthy of gratitude or admiration for their value, but rather things that are noticeable or measurable, as in “an appreciable difference between the two shades of green.” Appreciable comes, via French, from the Late Latin verb appretiare (“to appraise” or “to put a price on”), and is one of several English adjectives that can be applied to something that can be detected, felt, or measured. When it comes to vocabulary, it’s hard to put a price on having an abundance of options.
