What it means
Someone who looks blank, clueless, or a bit dozy, like the lights are on but nobody’s home. It’s not always calling them thick, more that they’ve missed the obvious moment. The word’s old, from gorm meaning understanding, so gormless is literally without it. Handy, and pretty satisfying to lob in an argument.
Usage examples
"Fire alarm’s going off and Gaz just stands there gormless, clutching his butty. I’m like, Ey up lad, shift it. He goes, Thought it were nowt."
"He just stood there with a gormless grin while everyone waited for an answer."
"Do not be so gormless, read the instructions before you start pressing buttons."
Where it comes from
Comes from the old northern dialect word gaum or gome, meaning sense, heed or notice, plus the suffix less. To be gormless is literally to be without gaum, lacking the basic wit to take notice of what is going on. So a gormless look is the blank, slack-jawed stare of someone who has not the faintest idea, and a gormless person blunders along with no clue and no initiative.
