Regular Verbs (Leaving Cert Spanish): Revision Notes
Regular verbs in the present tense
Overview
The present tense describes actions happening now or habitual actions. It's one of the most important tenses in Spanish as it forms the foundation for learning other tenses. Regular verbs follow predictable patterns based on their infinitive endings.
Spanish regular verbs fall into three groups based on how their infinitive forms end: -ar, -er, and -ir verbs. Each group has its own set of endings that you add to the verb stem (the infinitive minus the final two letters).
Regular verbs are called "regular" because they follow completely predictable patterns. Once you master these three patterns, you'll be able to conjugate hundreds of Spanish verbs correctly!
Rules & formation
To conjugate regular verbs in the present tense, follow these steps:
- Remove the infinitive ending (-ar, -er, or -ir) to find the stem
- Add the appropriate ending based on the subject pronoun and verb group
- The stem never changes - only the endings change
Critical Rule: The stem never changes in regular verb conjugations. This is what makes them "regular" - you simply remove the infinitive ending and add the new endings. The stem remains constant across all forms.
The endings for each group are:
- -ar verbs: -o, -as, -a, -amos, -áis, -an
- -er verbs: -o, -es, -e, -emos, -éis, -en
- -ir verbs: -o, -es, -e, -imos, -ís, -en
Notice that yo always ends in -o for all regular verbs, and nosotros/as always contains the vowel from the infinitive ending.

Common mistakes & tips
Understanding common errors will help you avoid them and improve your Spanish fluency. Here are the most frequent mistakes students make with regular present tense verbs:
Mistake 1: Forgetting to change the ending
- ❌ Yo bailar
- ✅ Yo bailo
Always remove the infinitive ending and add the correct present tense ending. Never use the infinitive form as a conjugated verb.
Mistake 2: Mixing up -er and -ir endings
- ❌ Tú vives → Tú comes (incorrect: Tú comis)
- ✅ Remember: -er verbs use "e" endings, -ir verbs use "i" in nosotros/vosotros forms only.
Mistake 3: Incorrect accent placement
- ❌ vosotros bailais
- ✅ vosotros bailáis
The vosotros forms of -ar and -ir verbs need written accents. This is crucial for proper spelling and pronunciation.
Mistake 4: Using English word order in questions
- ❌ ¿Tú comes qué?
- ✅ ¿Qué comes tú? or ¿Qué comes?
Spanish question words usually come first, unlike in English where they often come later in the sentence.
Memory tip: The yo form always ends in -o, making it easy to remember. Start there and build the other forms around it. This works for all regular verbs in Spanish!
Remember!
Key Points to Remember:
- Regular verbs follow three clear patterns based on -ar, -er, and -ir endings
- The verb stem never changes - only add the appropriate endings
- Present tense describes current actions, habits, and ongoing situations
- Watch out for accents in vosotros forms of -ar and -ir verbs
- Practice with common verbs like bailar, comer, and vivir to master the patterns
- The yo form always ends in -o across all three verb groups
