Quid pro quo

Quid pro quo (Latin for "this for that", many times understood by English speakers as "what for what" or "something for something" or even at times "one thing for another") is used to mean, in the English speaking world, a favour for a favour (in other linguistic contexts, such as Portuguese and French, it means a misunderstanding, a confusion – to take the this for a that and quid pro quo is quoted as do ut des, Latin for "I give, so that you give"). Quid pro quo is a legal term for the transaction of valued items or favours, in return for giving something of value. For a contract to be binding, it usually must involve consideration, that is, the exchange of something of quantifiable value, however, quid pro quo is widely used in the context of describing political favours, as given in apparent exchange for money. It is also widely known as a legally recognized type of sexual harassment in some countries.
