Pronunciation - Have to

Have to

When we use the verb 'have' in its modal form: have to meaning an obligation, the /v/ at the end of the word changes to an /f/. Also the vowel sound in the word to changes to a schwa - /ə/. Have to becomes /hæftə/.
Some examples of phrases where this might happen include:

• Mary and Joana have to be there by 9.
• We have to study for the test.
• You have to tell me the truth
• I always have to take the bus at 7 am
