If you want to make suggestions, can you only use 'could' or does 'can' also work? Please look at these examples. Which sentence would be correct?
Context: I would like to suggest something to someone:
1 You could talk to a teacher.
2 You can speak to a teacher.
3 Both
3 – so both.
The conjunctive is more polite – ie less intrusive – formulated.
No. 3: Both are okay. But no.1 is more appealing, more corresponds to a polite and cautious proposal.
It's both up, it's up to the context.
3.
