General prefixes:
* Co-: implies shared or joint, like "co-common" could mean something shared by many (but not necessarily the most common thing).
* Pan-: implies universal or widespread, like "pan-common" could describe something that's common to everyone or everywhere.
* Ubi-: means "everywhere," suggesting something that is commonly found in all places, like "ubi-common".
More specific prefixes:
* Pre-: signifies something that comes before, so "pre-common" could describe something that was common before a change.
* Post-: signifies something that comes after, so "post-common" could describe something that became common after a specific event.
* Hyper-: implies excessive or beyond normal, so "hyper-common" could describe something that is extremely common.
Other options:
* Widely: a more descriptive term, suggesting something that is common to a large extent.
* Commonly: an adverb form, describing something that happens frequently.
Ultimately, the best prefix depends on the context of your sentence and the specific meaning you want to convey.
