What is a prefix for the word temporary?

There isn't a common, single-word prefix specifically for "temporary." However, you can use prefixes to create related words with slightly different meanings:

* Pro- (meaning "before" or "in front of"): Protemporary (though not a common word, could imply something that *precedes* a temporary state).

* Semi- (meaning "half" or "partly"): Semitemporary (meaning something that is partly or somewhat temporary).

* Inter- (meaning "between" or "among"): Intertemporary (not a common word, could imply something that exists *between* temporary states).

You could also use other prefixes depending on the desired meaning, such as:

* Pseudo- (meaning "false" or "imitation"): Pseudotemporary (something that appears temporary but isn't).

* Quasi- (meaning "somewhat" or "nearly"): Quasitemporary (something that is almost temporary).

Ultimately, the most suitable prefix depends on the specific context and desired nuance.
