When you are directly addressing a person or persons that you would normally address as usted or ustedes, give formal commands by taking the yo form of the present indicative tense and changing the ending of -ar verbs to -e for singular (usted) commands or -en for plural (ustedes) commands and changing the ending of -er/-ir verbs to -a or -an. Because you are working from the yo form of the present indicative, the formal commands reflect the irregularities you find in irregular and stem-changing verbs.
