Variants

しろよshiroyocolloquial
よ makes the order personal — pressing and impatient rather than flatly cold, so between friends it nags rather than commands（早はやくしろよ・行いけよ・食たべろよ）.
くれkurecolloquial
くれる breaks the 一段 rule and gives くれ, never ×くれろ — ちょっと手てを貸かしてくれ, and the same shape carries the 〜てくれ request.
せよseyoliterary
the written imperative of する, and its 一段 partner 答こたえよ — exam papers, official orders and slogans（次つぎの問といに答こたえよ）.
