Irregular Future Tense Conjugations

Although mainly regular and easy to work with, there are some verbs in the future tense that have a certain root change before applying the standard future-tense suffixes (-é, ás, á, etc.)

The verb salir(to leave), for example, is NOT conjugated yo saliré. It creates a new form to be used in the future tense, saldr-. Once we know this irregular stem, we can put the first person singular ("yo") suffix on it. So the correct way to say "I will leave" is:

Yo saldré.

Other verbs that have irregular stems are:

Irregular Verb	New Root
poner	pondr-
salir	saldr-
decir	dir-
hacer	har-
venir	vendr-
poder	podr-
saber	sabr-

Notice that these verbs that are irregular are commonly used, as you have seen that many verbs are indeed irregular the more they are used in speech.
