This document discusses the fundamental parts of Spanish verbs, including verbs in the present tense. It covers the infinitive, ending, and stem of Spanish verbs. The infinitive is the basic unconjugated form ending in "r". The ending is the last two letters of the infinitive. The stem is what is left after removing the ending. It provides examples of regular -ar verbs and explains how to conjugate them by using the stem and applying emphasis to different vowels. It also discusses how the present tense can be used to express present, ongoing, and future actions in Spanish.
