Talking About the Future
'Haré' is the 'I' form of the verb 'hacer' (to do/make) for talking about the future. You use it to state what you will do, often as a plan or a promise.
Irregular Future Stem
Notice that 'haré' doesn't come from 'hacer + é'. The stem changes from 'hac-' to 'har-'. This happens with several common verbs in the future tense.
'Haré' vs. 'Voy a hacer'
Mistake: “Thinking 'haré' and 'voy a hacer' are completely different.”
Correction: They both mean 'I will do/make' and are often interchangeable. 'Voy a hacer' can feel a bit more immediate ('I'm going to do'), while 'haré' can sound slightly more formal or like a firm promise.
