Usage

Some usage guides insist that apt followed by an infinitive can or should be used to mean only “inclined, disposed”: He is apt to ignore matters he regards as unimportant. In fact, apt is standard in all varieties of speech and writing as a synonym for likely in contexts that suggest probability without any implication of a natural disposition toward: Hostilities are apt to break out if the confrontation is not soon resolved. She is apt to arrive almost any time now. See also liable, likely.

Related Words

Etymology

Origin of apt¹

First recorded in 1350–1400; Middle English, from Latin aptus “fastened, fitted, fitting, appropriate,” equivalent to ap(ere) “fasten, attach” + -tus past participle suffix

Origin of apt.²

First recorded in 1900–05

Explanation

Something apt is perfectly appropriate, clever and well-suited to the matter at hand. If your room is small and dark, “cave-like” would be an apt description. The wee cousin of aptitude, apt has the same root meaning of "strength and ideal appropriateness." An apt description or nickname is one that’s just right. Apt can also be used in the form "to be apt to" meaning "to be likely to" do something. You’re apt to use this word more now that you know precisely what it means!
