Answer 1

No there aren't. You simply use the present tense of the verb "haber" followed by the past participle of the main verb.

Ex Siempre he preferido montar en bici que a caballo. Preferir is a stem-changing verb, but has regular past participle. . I have always preferred riding a bicycle to horseback riding.

There are some irregular past participles, however. For example "abrir" is a regular verb with an irregular past participle--"abierto." I have opened the door.

"He abierto la puerta.'

To form the past participle with regular verbs, just remove the infinitive ending, "ar, er, Ir" and replace with "ado" for "ar" verbs and "ido" for "er" and "ir" verbs.

The question is weird to me, I wouldn't know whether to consider the change from haber to he or hemos a stem change, nor the irregulars (for some reason I still sometimes use ponido instead of puesto). But I think as you say they are probably not technic - bosquederoble, Apr 9, 2017

Haber is just an irregular verb. It does not fall into the category of "stem-changing" verbs. - Daniela2041, Apr 9, 2017
