Explanation
In this family the stem vowel doesn't diphthongize — it raises: e becomes i in the stressed boot forms. Pedir → pido; servir → sirvo; repetir → repito; vestir → visto.
The pattern exists only in -ir verbs. Nosotros, vosotros, and vos keep the e: pedimos, pedís, vos pedís.
Unlike e → ie verbs, the raised i spreads much further: preterite third person (pidió, pidieron), gerund (pidiendo), and the whole present subjunctive (pida, pidamos). Seguir adds a spelling change: sigo, sigues.
