Rule reminder
Italian derives adjectives from verbs using suffixes such as -ivo/-iva (produrre → produttivo), -bile (realizzare → realizzabile), -oso/-osa (vantaggio → vantaggioso), and -ale (natura → naturale). These adjectives are very frequent in formal and written Italian.
Which adjective means 'capable of being achieved' (from 'realizzare')?
