In the context of modality and adverbs, the construction “could + subject + possibly” is used to make requests more polite. By adding “possibly” to the sentence, it softens the request and adds a sense of politeness or tentativeness. This structure is often used to make requests in a more considerate or deferential manner.
Here’s an example to illustrate this usage:
- Direct Request: “Tell me how to fix this.”
- Polite Request: “Could you possibly tell me how to fix this?”
In the direct request, the speaker simply states the command, while in the polite request, the speaker uses “could” to express the possibility and adds “possibly” to make the request more courteous. The addition of “possibly” acknowledges that the person being asked may have other commitments or may not be able to fulfill the request.
By using this construction, the speaker shows respect and acknowledges the potential inconvenience the request might cause. It is a way of making the request more polite and allowing the person being asked to have the option to decline or fulfill the request based on their own circumstances.
Overall, the use of “could + subject + possibly” in making requests more polite is a way to express a sense of consideration and deference while seeking assistance or information.

*This is a very rare structure across corpora for a B1 structure. This point overlaps the more common and general: B1 questions with adverbs:
Could you possibly tell me how to fix this?
