| Mixing "have to" with "must" (they are different) | Know that "must" is more formal; "have to" is more common. | Use "must" in formal writing, "have to" in speech. |
| Using "have to" in negative sentences incorrectly | Always say "don’t have to" (not "not have to"). | Remember: Negatives require "don’t" + "have to." |
| Confusing obligation with permission | “Have to” = obligation; “can” = permission. | Use "can" for permission, "have to" for necessity. |
