combatirás
Combatirás is a Spanish verb form. It is the second-person singular future indicative of the verb combatir. In English, this translates to "you will fight" or "you will combat." The verb combatir itself means to fight, to combat, to struggle against, or to oppose. Therefore, "combatirás" is used to express an action of fighting or opposing that will take place in the future, directed at a single person being addressed informally (tú).
For example, in a sentence like "Tú combatirás la injusticia," the meaning is "You will fight injustice."
