Is there a simple one- or two-word term for this? Searching for it brings up all the contracts ever, but not a term… I’ve checked the Reverse Thesaurus, and it didn’t help.
Gotcha (clause)?
(tentative)
Disclaimer.
Contingent?
All-purpose all-encompassing universal escape clause.
Changeable?
Mutable?
Changeable is probably the closest… it’s for a story I’m writing about a shapeshifter, who doesn’t have too much control over his ability. Somebody asks him what he is, and he says… something simple, like changeable.
Changeable works, but I think “mutable” fits even better.
I like it. An apprentice shapeshifter. Will make for a great comedy. Write the screenplay!
Capricious, moody, volatile?
(The pragma volatile is used in a lot of programming languages for very similar semantics.)
The problem is that the phrase conveys two important things - changeable, and no notice of that change. The latter is arguably just as important.
That it is such a common phrase in many bits of legalese I am surprised it doesn’t have a name. Perhaps a Latin form could be crafted to suit.
Variable?
Morph. And he should be from a place called Orph. And have a catch-phrase–maybe something like “noo-nah, noo-nah.”
Turbulent. Terribly turbulent.
It does have an equivalent: Gotcha… Latin for “Oh, SNAP!”
Apparently the OP wasn’t interested in the legalese aspect however, but merely wanted a way to shorten the phrase “Subject to change without notice” and is satisfied with… Change(able).
You need to consider the etymology of each synonym carefully and pick the one you truly mean.
For instance, something volatile flies about on currents of air, someone erratic wanders (errs) about randomly astray, and someone capricious has an unruly, impulsive character.
The untrained shapeshifter sounds a bit erratic in your description.
Mercurial?
Conditional?
I like it!
Yes I’m a bastard, but I’m a bastard with your money.
