"Say 'uncle'!" is a chiefly North American expression demanding that the opponent in a contest submit. The response "Uncle!" is equivalent to "Mercy!", "Please!", "I give up!" or similar sentiment, and indicates submission.
In the United States and Canada, the idiomatic expression "Say 'uncle'!" may be used as an imperative command to demand submission of one's opponent, such as during an informal wrestling match or tickling. Similarly, the exclamation "Uncle!" is an indication of submissionâÂÂanalogous to "I give up!"âÂÂor it may be a cry for mercy, in such a game or match.
There are several theories on the phrase's origin including a phrase from the Roman Empire.
Due to heavy Irish immigration in eastern Canada and New England in the 19th century, it is likely an anglicization of the Irish 'anacal', meaning deliverance or quarter.
Another theory is that it derives from a phrase uttered by youngsters in the Roman Empire who got into trouble, (âÂÂuncle, my best of unclesâÂÂ).
A fanciful suggestion is that it may be based on a joke from 19th-century England about a bullied parrot being coaxed to address his owner's uncle.
Another suggested origin is from the English phrase âÂÂtime outâÂÂ, a plea to cease hostilities. The abbreviated usage "T.O." was mistaken for the Spanish âÂÂtÃÂoâÂÂ, which means "uncle".
There is a common analog in the Arabian Peninsula, the expression "" ([q]uwl 'aamiy), which means "say uncle".
In Canadian-French, the expression "Dis pardon, mon oncle" is often used in the same way. It means "Say excuse me, uncle".
In the Persian language too, there is the similar expression of úÃÂ÷ éñïà, which is said when someone requests to be forgiven while the expression also entails considerable humiliation.
