Step-by-step explanation:
When delving into the ustedes command form in Spanish, the focus shifts to irregular verbs, which deviate from standard conjugation patterns exhibited by regular verbs. These irregularities emerge as alterations in stems or endings, diverging from the conventional rules of conjugation. The ustedes command form, employed for issuing orders or instructions to a formally addressed group, showcases these irregular manifestations across various verbs.
