What are the most common irregular Spanish verbs and their conjugations

The most common irregular Spanish verbs include “ser” (to be), “estar” (to be), “ir” (to go), “tener” (to have), “hacer” (to do/make), “decir” (to say/tell), “venir” (to come), “poder” (to be able to/can), “querer” (to want), and “saber” (to know). These verbs are irregular because their conjugations deviate from regular patterns in various tenses.

Here are examples of their conjugations in the present indicative tense:

• Ser: soy, eres, es, somos, sois, son
• Estar: estoy, estás, está, estamos, estáis, están
• Ir: voy, vas, va, vamos, vais, van
• Tener: tengo, tienes, tiene, tenemos, tenéis, tienen
• Hacer: hago, haces, hace, hacemos, hacéis, hacen
• Decir: digo, dices, dice, decimos, decís, dicen
• Venir: vengo, vienes, viene, venimos, venís, vienen
• Poder: puedo, puedes, puede, podemos, podéis, pueden
• Querer: quiero, quieres, quiere, queremos, queréis, quieren
• Saber: sé, sabes, sabe, sabemos, sabéis, saben

These verbs often have irregularities such as stem changes (e.g., e→ie in querer), irregular first-person forms (e.g., hago for hacer), or completely irregular forms (e.g., soy for ser). Their conjugation irregularities appear across various moods and tenses, not just in the present indicative. ^{6, 7, 15}
