'destroyable' originates from the verb 'destroy' + the adjectival suffix '-able'. 'Destroy' comes into English via Old French 'destruire' from Latin 'destruere', and '-able' comes from Old French/Latin '-abilis' meaning 'able to be'. '"destroyable"' originates from '"destroy"' + suffix '"-able"', where '"destroy"' ultimately derives from Latin '"destruere"'.

'destroy' changed from Old French 'destruire' and Middle English 'destroien' and eventually became the modern English 'destroy'. The modern adjectival formation 'destroyable' followed from adding the suffix '-able' (from Old French/Latin) to 'destroy'. '"destroy"' changed from Old French '"destruire"' and Middle English '"destroien"' and eventually became modern English '"destroy"'.

Initially, the Latin 'destruere' meant to tear down or overturn; over time it evolved into the sense 'to ruin, demolish or put an end to', which is retained in the modern word 'destroy' and thus in 'destroyable' meaning 'able to be destroyed'. Initially, it meant 'to tear down/overturn', and over time it evolved into the current sense 'to ruin or demolish'.
