Past: unstepped
Past Participle: unstepped
This word originates from Old English, where 'un-' means not and 'step' (from 'stæpe') means a movement or pace. Therefore, 'unstep' refers to the act of not stepping or moving forward.
Think of 'not' ('un-') taking a 'step' — that's why 'unstep' means to not step forward.
