The Latin phrase quot; quid pro quo quot; means one thing for another. In latin, the original use of this term referred to a mistake, change one thing for another, or understand something wrongly. It currently indicates an error, confusion or misunderstanding, but it is also used to refer to a transaction or exchange of one thing for something equivalent. Example: Let esto quid pro quo, I'll help you but you come to my house.
In medieval latin also quiproquo. ( Something rather than another something. Latinism which originally meant a grammatical mistake in taking the interrogativo-indefinido pronoun 40 quid; nominative or accusative singular neutral ) instead of quo ( the same pronoun in the singular ablative case ). This grammatical error eventually became misconception that blended a thing or person with another similar. At the latino theatre was a dramatic appeal to create humor and conflict situations to confuse one character with another as in the host of Plautus, in which mercury is passed through lookalike, servant of general host.
