Irrevocable and Trusts

Irrevocable has a formal sound to it and is often used in legal contexts. Irrevocable trusts are trust funds that cannot be dissolved by the people who created them (the other kind is a revocable trust). An irrevocable credit is an absolute obligation from a bank to provide credit to a customer. Irrevocable gifts, under U.S. tax law, are gifts that are given by one living person to another and can't be reclaimed by the giver. But the word isn't always legal; we've all had to make irrevocable decisions, decisions that commit us absolutely to something.
