This document provides a quick reference guide to Spanish verb conjugations in different tenses including present, past (preterite), future, conditional, and past (imperfect). It lists the root, stem, and endings for the verbs "trabajar" (to work), "comer" (to eat), and "vivir" (to live) for each person (I, you, he/she/it, we, they) and tense. Notes are included on converting forms to be respectful "you" (usted/ustedes) by adding those words. The guide is intended to help with conjugating common Spanish verbs quickly across tenses.
