Sense: adjective/1

All four words describe someone whose behaviour annoys others through an excess of self-regard or cleverness, but they differ in focus. 'Smart-alecky' is the most specific: it targets a person's verbal style — rude, joking, and dismissive — and always carries strong disapproval. 'Cocky' is broader; it describes a confident, sometimes arrogant attitude that may appear in body language as much as speech, and occasionally it is used admiringly in sports contexts ('a cocky young quarterback'). 'Smug' is more about visible self-satisfaction than about words; a smug person may say nothing at all but still irritate everyone in the room. 'Wisecracking' overlaps most closely with smart-alecky because both involve verbal jokes, but wisecracking focuses on the desire to be funny, not necessarily on showing superiority. A wisecracking colleague might make you laugh; a smart-alecky one usually makes you roll your eyes.

Etymology

EnglishAmerican Englishslang

The word 'smart-alecky' comes from the noun 'smart aleck', which first appeared in US slang in the mid-1800s. 'Smart' already meant 'intelligent, clever', and 'Aleck' is a short form of the name Alexander. Some language historians trace it to a real person — a notorious thief named Alec Hoag who operated in New York City in the 1840s and was known for his cocky attitude. By the early 1900s, 'smart aleck' had settled into its modern meaning: a person who annoys others by showing off their cleverness. Adding '-y' changed the noun into an adjective meaning 'behaving like a smart aleck.'
