Word
don't have to
Definition
fixed phrase. you use this to say that something is not necessary. You have a choice, so you can do it if you want, but there is no rule or need to do it.
fixed phrase. a modal construction expressing the absence of obligation or necessity. It functions as the negative form of 'must' or 'have to' in terms of requirement, but unlike 'must not', it indicates that the action is optional.
Examples
“You don't have to wash the dishes; I'll do them later.”
“Since it is a holiday tomorrow, the employees don't have to come into the office.”
“In this specific jurisdiction, witnesses don't have to testify against their spouses if they choose to exercise their legal right to silence.”
Examples
simple
“You don't have to wash the dishes; I'll do them later.”
contextual
“Since it is a holiday tomorrow, the employees don't have to come into the office.”
complex
“In this specific jurisdiction, witnesses don't have to testify against their spouses if they choose to exercise their legal right to silence.”
Usage
the verb 'have' must be conjugated to match the subject (e.g., 'he doesn't have to').
Teaching tip
this is a major source of confusion for learners who assume it is the opposite of 'must' (prohibition); emphasize that 'must not' means 'don't do it' while 'don't have to' means 'it's your choice'.
Pitfall
You don't have to smoke here.
You mustn't smoke here.
learners often use 'don't have to' when they mean something is forbidden, rather than just optional.
