GRAMMAR POINTS TO REMEMBER
1 Asking for Permission: In an office environment, the safest and most common way to ask for permission or request a favor at a basic level is to place the word “Can” before the Subject.
- Example: Can I open the window?
- Example: Can you help me?
2 Golden Rules for Modal Verbs: * NEVER add the auxiliary verb “Do/Does” (Incorrect: Do I can…).
- NEVER use them with the “To Be” verb (Incorrect: Am I can…).
- The main verb following the subject must be in its BASE FORM (without “to”). Do not add “to”, “-ing”, or “-ed”. (Incorrect: Can I to use… / Can I using… -> Correct: Can I use…)
3 Responses: When refusing a request containing “Can”, you must also use the negative form of “Can”, which is “can’t” or “cannot” (do not use don’t or aren’t).
