'attemptable' originates from English, specifically from the verb 'attempt' plus the adjectival suffix '-able' (from Latin/Old French), where 'attempt' ultimately derives from Late Latin 'attemptare' (from 'ad-' + 'temptare').

'attempt' changed from Late Latin 'attemptare' into Old French forms such as 'atempter/atempter' and then into Middle English 'attempten', eventually becoming the modern English verb 'attempt'; the adjective 'attemptable' was formed later by adding the suffix '-able' to mean 'able to be attempted'.

Initially the Latin root meant 'to try' or 'to test'; over time the sense remained focused on trying, and the modern adjective 'attemptable' now specifically means 'capable of being attempted'.
