Continuous and continual can both mean roughly ‘without interruption’ ( five years of ~/continual warfare ), but ~ is much more prominent in this sense and can be used to refer to space as well as time, as in the development forms a ~ line along the coast . Continual , on the other hand, typically means ‘happening frequently, with intervals between’, as in the bus service has been disrupted by continual breakdowns .
