Abrir as an Imperative Negative Command

The imperative Negative commands are used to tell someone or a group of people what NOT to do. We do not give commands in the 1st or 3rd person which is why yo, él, ella, ellos, and ellas have been removed for this tense.

Abrir is regular when forming Imperative Negative Commands. 

Mostly we will give commands or tell someone we treat as (tú) what to do. Let’s learn how to conjugate that part first. 

To find the Negative Informal tú command of a regular verb follow these steps:

  1. Start with No
  2. Find the yo form of the verb in the present tense. 
  3. Take off the “o
  4. Add -es if it’s an -ar verb or -as if it’s and -er or -ir verb.
