Irregular "ir" stem changers in the preterite tense

Irregular "ir" stem changers in the preterite tense are called "stem-changing verbs". In Spanish grammar, stem-changing verbs are verbs that have a change in the stem of the verb in some forms, typically the preterite tense. The "ir" stem-changing verbs in the preterite tense are irregular in that the change in the stem is not predictable based on regular conjugation patterns. Instead, the stem change must be memorized for each individual verb. These verbs are often referred to as "e -> i" stem changers, as the stem change typically involves changing the "e" in the stem to an "i". However, there are also "o -> ue" stem changers and other patterns of stem change. Examples of "ir" stem-changing verbs in the preterite tense include "dormir" (to sleep), "sentir" (to feel), and "pedir" (to ask for).
