La fuite

s'enfuir = to run away

E.g. "il s'est enfui à toutes jambes" or "il a pris ses jambes à son cou" = he ran away as fast as he could. (une) jambe = leg and (un) cou = neck, so that literally translates into "he took his legs to his neck"

la fuite = flight, escape. E.g. prendre la fuite = s'enfuir
