When delving into verb conjugation, it’s crucial to grasp the nuances of Spanish irregular verbs. In fact, numerous frequently used verbs in Spanish fall under this category. In this comprehensive guide, we’ll explore all the essential details you need to understand about irregular verbs. Here’s what we’ll cover:

Understanding Irregular Verbs in Spanish

Irregular verbs in Spanish are those that deviate from the standard conjugation patterns observed in regular verbs. Unlike their regular counterparts, irregular verbs exhibit significant alterations in their root forms during conjugation.

Sometimes, irregular verbs also impact the conjugation endings. For instance, in the preterite tense, irregular endings often lose their accent marks.

While some may view stem-changing verbs as irregular due to their alterations, it’s essential to distinguish between these conjugation patterns. Irregular verbs undergo significant changes affecting their root and sometimes their conjugation endings, lacking a clear pattern. In contrast, stem-changing verbs like “dormir” exhibit minor spelling adjustments aimed at easing or preserving pronunciation.

Kindly observe: While the verb “ir” is irregular across most Spanish tenses, other verbs display irregularities only in specific tenses or with particular subject pronouns.

List of 18 Essential Spanish Irregular Verbs

Here’s a collection of common irregular verbs along with a conjugation chart displaying their expected alterations.

Ser – To be

The Spanish verb “ser” allows you to characterize people or things.

Ir – To go

Hacer – To do / To make

The root for the future tense (underlined) is also utilized to form the conditional. Additionally, observe that the conjugations of “hacer” for the present subjunctive use the irregular stem “hag”. This root showcases the same irregular change observed in the present indicative for the first person singular (yo).

Poder – To can / To be able

In other tenses, “poder” undergoes stem changes.

Poner – To put

The conjugations of “poner” are also irregular when forming commands. Remember to utilize the same root (underlined) for the future and conditional tenses. Finally, observe that the root for the present subjunctive is the same irregular root used for “yo” in the present indicative tense.

Saber – To know

Querer – To want

Decir – To say / To tell

Kindly observe: Verbs that end with ‘go’ in the present indicative (only for ‘yo’) utilize that irregular stem in the present subjunctive.

Haber – To have

Haber is a Spanish auxiliary verb, and it’s essential to become familiar with it because you’ll use it to form compound tenses.

Tener – To have

In Spanish, the verb “tener” serves as a suffix to form new verbs such as “detener” or “mantener.” Consequently, these words will also adhere to the conjugation patterns of “tener“.

Estar – To Be

In Spanish, the verb “estar” is employed to denote location and to describe the physical or emotional state of something or someone. It’s worth noting that in the subjunctive tense, the endings of these verbs carry accents.

Traer – To bring

Ver – To see / To watch

Salir – To leave

Observe that the present indicative of “salir” exhibits irregularity solely in the case of ‘yo‘. This irregular root will similarly be applied to construct the present subjunctive.

Venir – To come

Andar – To walk

The verb “andar” displays irregularity solely in its conjugation in the preterite tense.

Caber – To fit / To be room for
