The rule for formal commands, also known as direct commands, in Spanish is to take the present subjunctive form of the verb and modify it according to the pronoun. To form formal commands, follow these steps:
1. Take the present subjunctive form of the verb.
2. For regular verbs, drop the "-o" ending from the yo form of the present indicative and add the respective ending based on the pronoun.
- For -ar verbs, use the endings "-e" for Ud. (usted) and "-en" for Uds. (ustedes).
- For -er and -ir verbs, use the endings "-a" for Ud. (usted) and "-an" for Uds. (ustedes).
3. For irregular verbs, the verb form changes entirely. It's important to learn the specific irregularities for each verb.
