What is a prefix for the word perishable?

There isn't a commonly used prefix specifically for "perishable." The word itself already encompasses the idea of being susceptible to decay or spoilage.

However, you could use prefixes to create related words with different meanings, such as:

* Non-perishable: This prefix adds the opposite meaning, indicating something that does not decay or spoil easily.

* Semi-perishable: This prefix suggests something with a moderate shelf life, neither fully perishable nor completely non-perishable.

* Super-perishable: This prefix could be used to indicate something that spoils extremely quickly.

Ultimately, the best prefix depends on the specific meaning you want to convey.
