Acuminate (Adjective)

Pronunciation: [ê-'kju-mi-nêt]

Definition 1: Pointed or pointy, coming to a sharp point.

Usage 1: The verb is acuminate [ê-'kyu-mi-neyt] "to sharpen (an object or point in discourse)." The adjective is very common in the description of leaves that taper to a point (an acuminate leaf). But it may be used to refer to anything, concrete or abstract, that comes to a point.

Suggested usage: Have you ever wanted to call your boss a pointy-head without getting fired? Boy, do we have the word for you today! Because this word sounds like "acumen," unless your chief is too smart to deserve this epithet, his chest will swell with pride when you say, "Learning from someone with such an acuminate head on his shoulders as you have is so rewarding." The reward is hearing yourself tell off your boss without repercussion. Of course, you may enjoy this word in the usual way, too: "I thought it was a very acuminate point she developed; it could not have been clearer."

Etymology: Latin acuminat-us past participle of acumina-re "to make pointed, sharpen," akin to acumen, "a point, acuteness, cunning." Acumen is derived from acuere "to sharpen" itself from acus "needle" (Greek akis "needle"). Going back farther, the underlying root *ak- developed via Germanic into English "edge" and "ear" (ear or spike of grain). This root also metathesized to *ka- and acquired the suffix -men. The stem *ka-men turns up in English "hammer" and Russian kamen' "stone."
