Final answer:
Spanish has three categories of verbs, determined by the infinitive endings -ar, -er, and -ir, which dictate their conjugation patterns.
Step-by-step explanation:
In Spanish, there are three categories of verbs, based on the last two letters of the infinitive form. The categories are determined by these endings, which are:
For example, hablar (to speak) is an -ar verb, comer (to eat) is an -er verb, and vivir (to live) is an -ir verb. Each category follows its own set of conjugation rules in the various tenses and moods of the language.
