How do I conjugate Spanish verbs?

Spanish verbs are conjugated by removing the infinitive ending (-ar, -er, -ir) and adding the appropriate endings based on the subject and tense. Regular verbs follow predictable patterns, while irregular verbs have unique forms that must be memorized.

What are the main Spanish verb tenses?

The main Spanish verb tenses are: Present (presente), Preterite (pretérito), Imperfect (imperfecto), Future (futuro), Conditional (condicional), and Subjunctive (subjuntivo). Each tense is used in different contexts to express when an action occurs.

What is a stem-changing verb in Spanish?

Stem-changing verbs (verbos con cambio radical) change their stem vowel in certain conjugations. Common patterns include e→ie (pensar→pienso), o→ue (poder→puedo), and e→i (pedir→pido). These changes typically occur in all forms except nosotros and vosotros in the present tense.
