Despite the fact that the following verbs follow the ending-pattern of regular verbs in the preterite, such as hablar, ––habl-é, habl-aste, habl-ó, habl-amos, habl-asteis, habl-aron–– they do require a spelling change in the first person singular. For this reason, they are not regarded as regular verbs, but rather irregular, and they are commonly referred to as spelling-changing verbs. They are grouped below by the ending they share in the infinitive, which determines their spelling change in the preterite.
Notice an accent is required in both the first person and third person singular.
1. infinitive ends in –car: spelling change: c --> qu
