Assieds-toi ! Assieds-toi ! Sit down! These two look exactly the same to me or I can not see. Thank you Chris in advance!

Hi Fiona,

depending on which conjugation of "asseoir" you prefer, the imperative changes accordingly:

Assieds-toi -- Assois-toi
Asseyons-nous -- Assoyons-nous
Asseyez-vous -- Assoyez-vous

They are all identical to the corresponding forms in present tense.

There are also two possible pronunciations of "Assieds-toi", so one of the examples repeats it: "Assieds-toi! Assieds-toi!". The accompanying sound file demonstrates the two pronunciations.

Thank you Chris. That was very helpful as always!
