Truly Irregular Verbs in the Preterit

A few verbs in the preterit follow no patterns and must be memorized. The verbs ir (to go) and ser (to be) are conjugated exactly the same in the preterit. The context of a sentence determines which verb is being used. Also, any form of ir is always followed by the preposition a. Table presents the preterit forms of two of the most common verbs in the Spanish language.


Dar (to give) and ver (to see) are usually learned together in the preterit because their forms are similar. Ver uses the regular endings for a normal ‐er verb in the preterit and is only irregular because it does not have accent marks. The verb dar is strange because it is conjugated like ver even though it is an ‐ar verb. Notice that there are no accents on any of the forms in Table and that the forms of dar are not the normal forms for an ‐ar verb.
