WRONG:

STRAIGHTJACKET

RIGHT:

STRAITJACKET

The old word “strait” (“narrow, tight”) has survived only as a noun in geography referring to a narrow body of water (“the Bering Strait”) and in a few adjectival uses such as “straitjacket” (a narrowly confining garment) and “strait-laced” (literally laced up tightly, but usually meaning narrow-minded). Its unfamiliarity causes many people to mistakenly substitute the more common “straight.”

See also “dire straights.”
