¿Por qué doblar? Para mantener la vocal corta: hoping (hope, esperar) ≠ hopping (hop, saltar). Solo si la última sílaba es tónica: begin → beginning, prefer → preferred, pero visit → visited, open → opening. El inglés británico dobla también la -l final: travel → travelled (EE. UU.: traveled). Nunca se doblan w, x, y: fixing, showing.
