Hi Nehal Rohit,

In fact, the only truly irregular verbs in terms of conjugation in the imperative are the verbs être, avoir, and savoir.

The other normally irregular verbs like aller, faire, prendre, etc. follow the normal imperative formation of all verbs -

va, allons, allez

fais, faisons, faites

prends, prenons, prenez 

etc.

Take a look at the following Kwiziq lesson on how the imperative works -

https://french.kwiziq.com/revision/grammar/conjugate-regular-verbs-in-l-imperatif-imperative

and note that regular verbs ending in -ER  drop the -s in the tu form -

regarde

achète

etc.

Bonne Continuation!
