The steps to conjugate a regular verb in the Spanish present tense are: Identify the verb’s infinitive form (ar, er, or ir). Drop the infinitive ending. Add the conjugation ending to the root. The infinitive form of a verb defines the endings you must use when conjugating.

To make the present tense in Spanish, you take the verb stem and then add the appropriate ending. The ending depends on the pronoun (I/you/he/etc.) and verb type (-ar/-er/-ir). The root or stem of the verb is the part before -ar/-er/-ir. Here are the stems of the three Spanish verbs we saw above: bailar → bail- vivir → viv- comer → com-

To conjugate a verb in the present indicative, remove the infinitive ending of the regular verb, in this case -ar, -er or -ir, and replace it with an ending that gives an indication as to "the person" that is performing the action of the verb. For example, hablar is the infinitive of a common regular verb ending in -ar.
