Could someone suggest what preposition to use after 'Follow-up'? Is it 'on' or 'of' or 'to'?
The background to the question above is an event that has happened, and (which) needs to be 'followed up': for example, consider the following sequence of events:
- a person enters into an email conversation (series of back and forth emails getting exchanged)
- After a while, he wants to sends a separate mail to pursue (follow-up) the earlier matter.
The question is, what should he use as the subject of this new email. Should it be:
- (a) Follow-up on the earlier matter (he means to say, I am following up on the earlier matter)
- (b) Follow-up of the earlier matter (meaning - this new email is a follow-up of the earlier matter)
- (c) Follow-up to the earlier matter (intention to state that the new email is a follow-up to the matter that was earlier discussed)
