Etymology

Origin of lackluster

First recorded in 1590–1600; lack + luster 1


Explanation

Lackluster is a compound adjective that means what it sounds like: if something is lackluster it lacks luster; in other words, it is without brilliance, shine, or vitality. Think dull. Shakespeare gave us the compound lackluster, first using the term in his play As You Like It. In 2:7, the character Jacques says, "And then he drew a dial from his poke, And, looking on it with lack-lustre eye..." Since Shakespeare first coined this word, it has been used to describe anything "blah"; lackluster sales would worry shop owners and a lackluster prom dress might help you blend in with the wallpaper.
