The short answer
Slight and sleight are pronounced the same but mean very different things. Slight is common: it works as an adjective meaning small, a verb meaning to insult by disregard, and a noun meaning an insult. Sleight is rare outside one phrase, sleight of hand, where it means skillful, often deceptive, dexterity. Confusing the two usually happens in writing, since the words sound identical when spoken.
What slight means
As an adjective, slight means small or minor, as in a slight delay. As a verb, to slight someone means to insult them by treating them as unimportant, often by ignoring or neglecting them. As a noun, a slight is the insult itself. Example: She felt slighted when her name was left off the invitation. Example: He meant no slight by arriving late; the traffic was unusually bad.
Slight can also describe a person's build, meaning thin or slender, as in a slight young man stood near the doorway. This physical sense is unrelated to the insult meaning, so context usually makes clear which one a writer intends, and both remain far more common in everyday English than sleight.
What sleight means
Sleight means skill or cleverness, especially the kind used to deceive, and it appears almost exclusively in the phrase sleight of hand, describing a magician's quick, practiced dexterity. Example: The magician's sleight of hand fooled the entire crowd. Not: The magician's slight of hand fooled the entire crowd, which swaps in the far more common but incorrect word.
Occasionally sleight appears outside that phrase in more formal or literary writing, still meaning cunning or deceptive skill, as in he managed the negotiation with considerable sleight. This use is rare enough that most readers only ever encounter the word inside sleight of hand, which is worth keeping in mind.
Why people mix them up
Slight and sleight share the same pronunciation and a similar shape on the page, and sleight almost never appears outside its one set phrase, so writers default to the more familiar slight instead. Spellcheckers do not always catch the error, since both are valid words in isolation, so the mistake often slips into print.
The confusion also spreads because slight of hand looks like a perfectly reasonable phrase on its own, describing something done with small, quick movements. That plausible-sounding logic is exactly why the misspelling persists in casual writing, marketing copy, and even some published fiction, despite being incorrect.
Remember it
Picture the letter e in sleight standing for expert, since sleight of hand always describes an expert, practiced skill, usually involving trickery. Slight, without that extra letter, keeps its plainer meanings: small, or a small insult. If the sentence is not about a magician's hands, the word you want is almost certainly slight, since sleight has essentially no other everyday use worth remembering.
