# 🛠️ Auxiliary Verbs Auxiliary verbs help form different tenses, moods, and voices in Spanish, so knowing them lets you express time, intention, and nuance more precisely. This guide covers the main auxiliaries like *haber*, *estar*, and *ir* when they function to help other verbs. --- ## Haber *Haber* is the key auxiliary for forming compound tenses like the perfect, and it appears as *he*, *has*, *ha*, etc. when you link it to a past participle. This structure shows actions that are completed relative to a reference time. --- ### Present Perfect <{ "type":"quiz","name":"haber-present-perfect","topic":"spanish/parts-of-speech/auxiliary-verbs","exercises":[{"name":"1","quiz":"haber-present-perfect","topic":"spanish/parts-of-speech/auxiliary-verbs","type":"exercise","question":"fill-in-blank","category":"conjugation","text":"Yo ___ (haber) terminado la tarea.","answer":["he"],"translation":"I have finished the homework.","emoji":"📝","explanation":"Present perfect is formed with the present of haber + past participle."},{"name":"2","quiz":"haber-present-perfect","topic":"spanish/parts-of-speech/auxiliary-verbs","type":"exercise","question":"fill-in-blank","category":"conjugation","text":"Ellos no ___ (haber) llegado todavía.","answer":["han"],"translation":"They have not arrived yet.","emoji":"⏳","explanation":"Use 'han' for ellos/ellas/ustedes in the present perfect."},{"name":"3","quiz":"haber-present-perfect","topic":"spanish/parts-of-speech/auxiliary-verbs","type":"exercise","question":"multiple-choice","category":"rule","prompt":"Which of these sentences correctly use 'haber' to form the present perfect?","correct":["Hemos comido en ese restaurante","¿Has visto mis llaves?"],"incorrect":["He siendo feliz hoy","Haben terminado la clase"],"emoji":"✅","explanation":"The present perfect pairs haber (he, has, ha, hemos, habéis, han) with a past participle.

You conjugate *estar* according to time and subject, then add the gerund like *hablando*. --- ### Present Progressive --- ### Past Progressive --- ### Future Progressive --- ## Ir *Ir* can function as an auxiliary in periphrastic constructions like *ir a* + infinitive to express near future intention. It helps signal planned actions rather than completed ones. Conjugate *ir* and follow with *a* and the infinitive. --- ### Near Future --- ### Usage --- ## Other Periphrastic Auxiliaries Spanish also has other auxiliary-like verbs that add nuance, such as *volver a* for repeated actions, *acabar de* for recent events, and *seguir* for ongoing ones. These helping verbs combine with infinitives to fine-tune meaning. --- ### Volver a --- ### Acabar de --- ### Seguir --- ## Summary Auxiliary verbs like *haber*, *estar*, and *ir* shape how you express time and aspect in Spanish, while periphrastics add layers of meaning.
