E to I stem changes in the Spanish Past Progressive Tense affect certain -ir verbs when forming the gerund to express ongoing past actions. This change occurs in the stem before adding the -iendo ending.
For example, ‘pedir’ (to ask for) becomes ‘pidiendo’ in the gerund form. This stem change is maintained throughout the Past Progressive tense when combined with the imperfect of ‘estar’.
