'implementable' is formed in English by adding the adjectival suffix '-able' to the verb 'implement'. 'Implement' ultimately originates from Latin, specifically the Medieval Latin/Latin past participle 'implementum' (from the verb 'implēre'), where the root elements 'in-' meant 'into' and 'plēre' meant 'to fill'.

'implement' entered English via Middle English and Anglo-French from Medieval Latin 'implementum' (from Latin 'implēre'). Later, English productivity added the suffix '-able' (from Latin '-abilis' via Old French) to create the adjective 'implementable'.

Initially, Latin 'implēre' meant 'to fill up' or 'to fulfill'; over time meanings shifted toward 'to fulfill, carry out, or make complete', and the modern adjective 'implementable' now means 'capable of being carried out or put into effect'.
