Capable of being made better or improved; susceptible to improvement or amelioration.
From 'ameliorate' (to make better, from Latin 'melior,' better) plus the suffix '-able' (capable of). The root 'melior' relates to 'better' and 'optimize.'
The word 'ameliorable' is optimistic by definition—it suggests that no situation is hopeless, which is why reform movements and social change advocates use it to argue that even the worst conditions can be improved.
