NARKED

Think of slang for informing on someone, often used in crime dramas when a suspect turns against their accomplices. The past tense of this word fits here.

"Squealed" hints at the idea of informing or snitching, which is where "narked" comes in—it's slang for reporting someone to authorities. The "Var." part is short for "variant," signaling that the answer is a less common or alternative form of the word. Here, "narked" is a British slang variant of "nark," meaning to complain or inform on someone, fitting both the definition and the wordplay.
