Need to write sentences with positive/negative and informal/formal commands.

Question

I need to create sentences with commands using the following words: organizar (informal); hacer (informal); limpiar (formal Ud.); and Poner (Formal (Uds.). I don't understand commands. Also, I need to make them positive and negative. I don't want you to give me the answers but rather a better method of understanding commands. Thank you.

Answer 1

Well, I'll try my best to explain how I understand it...

Positive commands :

For informal commands (tú form) you only write the verb in the third person singular form of the present tense. eg: Hablar : él habla (3rd person singular) -> Habla Comer : él come-> Come

For formal commands (usted and ustedes forms), you will write the verb in the third person singular (for usted) and third person plural (for ustedes) forms of the present tense BUT you will use the endings for the opposite verb groups (AR verbs will take ER and IR verb endings, and ER and IR verbs will take AR verb endings). eg: Hablar: Habl e (usted) and Habl en (ustedes). Comer : Com a (usted) and Com an (ustedes).

Negative commands :

For informal negative commands, you begin with the word "No", followed by the verb form which will be conjugated in the second person singular of the present tense but with the opposite endings (just as we did above). eg: Hablar : No habl es. Comer : No com as.

For formal commands, all you need is to add "No" before the verb form (which is obtained the same way as shown above). eg: Hablar: No habl e; No habl en. Comer : No com a, No com an.

Obviously there are verbs that are irregular such us hacer, poner and many more, but these are basically the rules. Hope I've helped.
