* They all use the same endings: The endings for the future tense are the same for all three conjugations.
* -é, -ás, -á, -emos, -éis, -án
* They all form the future stem with the same process:
* The future stem is formed by adding the infinitive ending (ar, er, ir) to the stem of the verb.
* Examples:
* Hablar --> Habl-ar --> Habl- + endings
* Comer --> Com-er --> Com- + endings
* Vivir --> Viv-ir --> Viv- + endings
* They all follow the same conjugation pattern: The future tense conjugation pattern is consistent across all three conjugations. You simply combine the future stem with the corresponding ending based on the subject pronoun.
In summary, even though the infinitives look different, they all behave the same way in the future tense.
