What is a prefix for the word around?

There isn't a common prefix used specifically for the word "around." "Around" is already a complete word with its own meaning.

However, if you're looking for a prefix to create a related word, you could consider:

* Circum-: This prefix means "around" or "surrounding," and is often used to create words like "circumnavigate" (to sail around) or "circumference" (the distance around a circle).

* Peri-: This prefix also means "around" or "surrounding," and is often used in scientific terms like "pericardium" (the membrane surrounding the heart) or "periphery" (the outer edge or boundary).

These prefixes can be used to create words that relate to the concept of being around something, but they wouldn't be direct prefixes for "around" itself.
