General Options:
* Pre-: This implies something happening before the act of seeing, like "pre-sighting" or "pre-visualizing". It doesn't necessarily imply "ahead".
* Pro-: This prefix suggests moving forward or anticipating, which could work for "pro-sighting" or "pro-visioning" to imply seeing into the future.
* Fore-: This is the most common and straightforward prefix for "ahead", suggesting "foresight" or "foreseeing".
More Specific Options:
* Anti-: This prefix indicates anticipation or prevention. "Anti-sighting" might be used in a scenario where you want to prevent something from being seen.
* Post-: This might be used in a context where you are reflecting on a past sight, like "post-sighting analysis".
* Retro-: Similar to "post-", this prefix suggests looking back, like "retrospective sighting".
Ultimately, the best prefix will depend on the specific context and what you're trying to communicate.
Instead of a single prefix, you could also consider using phrases like:
* Seeing ahead
* Anticipating what's coming
* Looking forward
* Visualizing the future
These phrases are clear and concise, and they convey the meaning of "sight ahead" without the need for a prefix.
