Auxiliary verb used in perfect tenses avoir avere haver haber ter

 

The periphrastic past in Catalan is an alternative to the preterite. It is formed by using anar as an auxiliary verb followed by the infinitive.

vaig deure
vas deure
va deure
vam deure
vau deure
van deure

There is an alternative form of the imperfect subjunctive in Spanish, which is more similar to Portuguese. Simply replace -ra- with -se- for all conjugations:

debiera / debiese
debieras / debieses
debiera / debiese
debiéramos / debiésemos
debierais / debieseis
debieran / debiesen

The future subjunctive is only used in formal or literary Spanish, but it is easy to conjugate since it is nearly identical to the imperfect subjunctive forms. The future subjunctive in Portuguese is very common and the same endings are used for the personal infinitive (see below).

Spanish Portuguese
debiere dever
debieres deveres
debiere dever
debiéremos devermos
debiereis deverdes
debieren deverem

The personal infinitive in Portuguese uses the infinitive as the stem + the endings of the future subjunctive.

dever
deveres
dever
devermos
deverdes
deverem

There is an alternative form of the past perfect in Portugueuse which only uses one word rather than an auxiliary verb + past participle. These conjugations are quite similar to the imperfect subjunctive conjugations using -ra- in Spanish. However, this simple form is only used in formal or literary Portuguese. (Note that the imperfect subjunctive in Spanish using -ra- can also be used in formal or literary language as an alternative to the compound past perfect.)

devera
deveras
devera
devêramos
devêreis
deveram
