* Pre-: This is the most common prefix meaning "before." It's very versatile and can be used in a variety of contexts.
* Precaution: A measure taken beforehand to prevent something bad from happening.
* Ante-: This prefix also means "before" and is often used to indicate something that comes earlier in time or order.
* Ante-caution: (While not a common word) could be used to describe a warning or signal given before a caution.
* Pro-: While primarily meaning "for" or "in favor of," "pro-" can sometimes indicate something that happens before.
* Pro-caution: (Again, not a common word) could describe an action taken in preparation for a cautionary situation.
Important Notes:
* The prefixes "pre-" and "ante-" are the most direct and common choices for indicating "before" in the context of caution.
* While "pro-" can sometimes indicate something that happens before, it's more commonly used to denote support or favor.
* When using these prefixes, ensure the resulting words are grammatically correct and make sense in the context of your writing.
