Affirmative Informal (Tú) Commands
Tú commands are the singular form of informal commands. You can use affirmative tú commands to tell a friend, family member of the same age or younger, classmate, child, or pet to do something. To tell somebody not to do something, you would use a negative tú command. This article covers affirmative informal commands (also called informal imperative) in all their forms.

Affirmative Tú Command Forms
For regular verbs, you will simply use the third-person singular form of the present indicative to form an affirmative tú command.
For verbs that end in -ar: Add the third-person singular ending -a to the stem.
For verbs that end in -er: Add the third-person singular ending -e to the stem.
For verbs that end in -ir: Add the third-person singular ending -e to the stem.
For verbs with stem changes or spelling changes in the present tense, the stem or spelling change also applies in informal command form.
|Close the door.|
|Move those chairs.|

Punctuation to the Rescue!
Because the informal tú command has the same conjugation form as the third-person singular, it is helpful to include exclamation points to indicate urgency or the name of the person you are commanding followed by a comma. Without the comma, a sentence could be confused with the third-person singular present indicative. Compare the following sentences written with different punctuation:
|She buys the shirt.||Present indicative|
|Buy the shirt!||Informal imperative|
|Alicia buys the shirt.||Present indicative|
|Alicia, buy the shirt.||Informal imperative|
