cuckoo
word
Definition
A "cuckoo" is a type of bird known for its call and for laying its eggs in other birds' nests. It can also refer informally to someone acting a bit crazy or odd.
Usage & Nuances
"Cuckoo" is usually used for the bird, but informally in British English it can mean someone is crazy or eccentric ('He's gone cuckoo!'). It's common in the phrase "cuckoo clock." Don't confuse this with "cocoa" (the drink) or "cuckold" (which is unrelated and more adult).
