Avalize

This sounds really intense. Like, "doctor, don't avalize her yet! Let's at least wait for those last test results to come in." But it's actually a financial term.

It means that a bank (or some other financial institution) puts an aval on something. An aval is a kind of endorsement or guarantee (See: Aval). Maybe a little intense if there's big money involved, but not call-the-doctor intense.
