Quid pro quo

*Antichristus*,^[1] a woodcut by Lucas Cranach the Elder of the pope using the temporal power to grant authority to a ruler contributing generously to the Catholic Church

Quid pro quo (Latin: "something for something"^[2]) is a Latin phrase used in English to mean an exchange of goods or services, in which one transfer is contingent upon the other; "a favor for a favor". Phrases with similar meanings include: "give and take", "tit for tat", "you scratch my back, and I'll scratch yours", "this for that,"^[3] and "one hand washes the other". Other languages use do ut des to express a reciprocal exchange, which aligns with the Latin meaning,^[4] whereas the widespread use of quid pro quo in English for this concept arose from a "misunderstanding".^[5]
