How do you form the imperfect tense in Spanish?

To form the imperfect tense in Spanish, first you take the infinitive of the verb, then you chop off the -ar/-er/-ir to be left with the stem. eg. jugar -> jugar -> jug..... or comer -> comer -> com..... Then you add... -aba , -abas , -aba , -ábamos , -abais , -aban for -ar verbs. And... -ía , -ías , -ía , -íamos , -íais , -ían for -ir and -er verbs. There are luckily only 3 irregulars in the imperfect tense: 1) Ir (To go) iba , ibas , iba , íbamos , ibais , iban 2) Ser (To be) era , eras , era , éramos , erais , eran. 3) Ver (To see) veía , veías , veía , veíamos , veíais , veían_{*Please note the formatting may have changed on submission}
