invalidated vs unvalidated

[Jaguar]

Is unvalidated a word? I want to use a word to describe something that has not been validated.

Invalidated strikes me to mean made invalid, while Unvalidated makes me think: not validated. But I don't think unvalidated is a word.

Is unvalidated correct, or do I want a different word?

"Unvalidated" is not a proper word. If you do not want to use "invalidated" maybe you can use "unevaluated".

Although unvalidated does not (yet) appear in Webster's unabridged, I think it can be considered a "proper" word.

I agree with Jaguar's differentiations.

For example, a bank customer gets free parking if he has his parking stub validated. Validation consists of having a bank employee stamp the stub. If the customer presents the stamped stub to the lot attendant, he doesn't have to pay.

However, if the customer forgets to get the stub stamped, it remains unvalidated.

The word unevaluated is not the equivalent of unvalidated. The word evaluate means to appraise as to value or worth. A painting or a term paper could be said to be "unevaluated" until someone gets around to evaluating it.
