This document discusses how to form affirmative and negative commands using Ud. (formal you) and Uds. (formal you plural). It explains that the present tense yo form is used and the "o" is dropped, similar to negative tú commands. For -ar verbs, add -e or -en, for -er/-ir verbs add -a or -an. Affirmative and negative Ud./Uds. commands follow the same spelling changes and irregular forms as negative tú commands. Reflexive pronouns are attached to affirmative commands and placed before the verb for negative commands. Examples of commands using Ud. and Uds. are provided.
