Novate
To replace by something new; specifically in law, to replace by a new obligation, debt, etc.
Hence …
Novation
1. The introduction of something new; a change, an innovation. (Scots, obsolete)
2. The substitution of a new debtor, creditor, contract, etc. in place of an old one.

I’ve most commonly encountered novation in the second sense and in the situation of company acquisitions etc. X has a contract to provide a service to Y; when X is bought by Z the contract with Y is novated from X to Z, but only by mutual agreement of the parties through a legal process. It applies equally to company contracts and to moving your bank account during a take-over/acquisition.
The earliest use recorded by the OED is from Speed’s History of Great Britain of 1611.

An Oriental (mostly Arabic?) term for a gratuity, present of money, tip or bribe. Or as a verb, to give the same.
A burlesque verse form in which vernacular words are used in a Latin context, with Latin constructions etc. It can also be used where the verse is based on Greek instead of Latin; and thus loosely to any form of verse in which two or more languages are mingled together.
