stay still
Reste tranquille ou je te frappe.
Stay still or I'll hit you.
Reste tranquille, Madruga, reste tranquille !
Stay calm, Madruga, stay calm!
— La Cité des hommes (2007)
Reste tranquille pendant que je parle.
Stay quiet while I speak.
Reste tranquille deux minutes, je te fais un pansement.
Stay still for two minutes, I'll put a bandage on you.
