What language is capiche?

"Capiche" is an informal, often humorous, way of saying "understand?" It's an English word, though it's a borrowed phrase from Italian.

In Italian, "capire" means "to understand". The word "capiche" is a shortened version of "capisci?" which is the informal, familiar way of saying "do you understand?" in Italian.

While "capiche" itself is not a real Italian word, it's been adopted into English slang and is used to emphasize understanding or agreement, often with a playful or ironic tone.
