The irregular future tense (tendr-, har-, podr-...)

Some of the most common Spanish verbs have irregular stems in the future tense. The endings remain exactly the same (-é, -ás, -á, -emos, -án), but you attach them to a modified stem instead of the infinitive.

These irregular stems apply to all subjects:
