Instruction: Overview of Spanish verb conjugation

Verb conjugation is a cornerstone of the Spanish language. It involves altering the form of a verb to convey who is performing the action and when the action takes place. This chapter will provide a comprehensive overview of Spanish verb conjugation, breaking down the key elements you need to know to master this essential aspect of the language.

The Structure of Spanish Verbs

Spanish verbs in their base form are known as infinitives and can end in one of three ways: -ar, -er, or -ir. Each of these endings determines the pattern of conjugation that the verb will follow. Here’s a quick look at each type:

  • -ar verbs: e.g., hablar (to speak)
  • -er verbs: e.g., comer (to eat)
  • -ir verbs: e.g., vivir (to live)

These endings provide the foundation for how verbs are modified to match different subjects and tenses.

Conjugation Patterns


Conjugation patterns are sets of rules that dictate how verbs change based on their endings and the subject performing the action. There are regular and irregular patterns:

1. Regular Verbs: Follow a predictable pattern based on their infinitive endings. For example, the present tense conjugation of “hablar” (to speak) is:

  • yo hablo (I speak)
  • tú hablas (you speak)
  • él/ella/usted habla (he/she/you speak)
  • nosotros/nosotras hablamos (we speak)
  • vosotros/vosotras habláis (you all speak)
  • ellos/ellas/ustedes hablan (they/you all speak

2. Irregular Verbs: Do not follow regular conjugation patterns and must be memorized individually. Examples include “ser” (to be), “tener” (to have), and “ir” (to go).

Tenses and Moods

Spanish verbs change form to indicate tense (when the action happens) and mood (the attitude of the speaker towards the action). The main tenses include present, past (preterite and imperfect), future, and conditional. Each tense has its own set of conjugation rules.

  • Present Tense: Indicates actions happening now.
  • Preterite Tense: Describes actions that were completed in the past.
  • Imperfect Tense: Describes ongoing or habitual past actions.
  • Future Tense: Describes actions that will happen.
  • Conditional Tense: Describes actions that would happen under certain conditions.

Moods include indicative, subjunctive, and imperative:

  • Indicative Mood: States facts and reality (e.g., “Yo hablo” – I speak).
  • Subjunctive Mood: Expresses doubt, wishes, or hypothetical situations (e.g., “Espero que hables” – I hope you speak).
  • Imperative Mood: Gives commands or requests (e.g., “Habla” – Speak).

Subject Pronouns

Subject pronouns indicate who is performing the action of the verb. In Spanish, they include:

  • yo (I)
  • tú (you – informal singular)
  • él/ella/usted (he/she/you – formal singular)
  • nosotros/nosotras (we)
  • vosotros/vosotras (you all – informal plural)
  • ellos/ellas/ustedes (they/you all – formal plural)

These pronouns are often omitted because the verb endings usually indicate the subject.

Stem Changes and Spelling Changes

Some verbs experience changes in the stem or spelling to preserve pronunciation or follow traditional patterns. For example:

  • Stem-Changing Verbs: Verbs like “pensar” (to think) change the stem vowel in certain forms (e.g., “yo pienso”).
  • Spelling Changes: Verbs like “jugar” (to play) change their spelling to maintain pronunciation (e.g., “yo juego”).

Importance of Practice

Mastering Spanish verb conjugation requires consistent practice. Utilizing verb tables, engaging in regular exercises, and applying verbs in real-life contexts can significantly improve your proficiency. Practice helps internalize conjugation patterns and irregularities, making it easier to use verbs correctly in conversation and writing.
