We often associate the phrase with magicians or three-card-monte dealers—people adept at moving things with the fingers without detection. A synonymous term is legerdemain, from a French phrase meaning “light of hand.”

What Does "Sleight" Mean?

The sleight in sleight of hand is its own word, one meaning “deceitful craftiness” or “stratagem” as well as “dexterity or skill.” It derives via Middle English from an Old Norse word, slœgr, meaning “sly” (and from which sly is also derived). A sleight, essentially, is an instance of being sly in one's movements.

Sleight is pronounced to rhyme with height. A homophone of sleight is slight, which as an adjective can mean “having a slim or delicate build” or “small of its kind or in amount” (as in “a slight lead in the polls”).

Confusion with Slight

As a verb, slight can mean “to treat as slight or unimportant” or “to treat with disdain or indifference,” as in “she felt slighted by her co-worker when she wasn’t invited to the party.” The noun slight can refer to an act of instance of slighting or insulting another. Slight finds its origin in Middle English, from a word meaning “smooth or slight,” with a likely Old English ancestor found in a term meaning “level with the ground.”

Once in a while you will see the phrase sleight of hand rendered mistakenly as slight of hand. This interpretation is understandable when you think of the movements a magician makes as being barely noticeable (just as slight means "barely noticeable" in “felt a slight tremor”). But this spelling isn’t anywhere near common enough to become standard.
