How are "verbs like gustar" different than normal verbs?

These verbs are not common because of their meaning in English but rather by how they are conjugated. Each of these words end in -ar. You can conjugate all of these verbs using the following rules: yo: -o tu: -as el/ella/Ud: -a nosotros/as: -amos vosotros/as: -ais ellos/ellas/ Uds: -an

Explanation:

cuatros, tamboras, and gaita zuliannas maracas, guitars, and drums harps, violins, and piccolos

corras is the only one that is informal but doesn't follow the suffix rule. correr is the verb. corre is the formal verb form. corra would be used as the formal is corre ended with an a.

your best bet would be corras, it's the only one that is informal but is still wrong
