'balanceable' originates from Modern English, specifically formed from the word 'balance' + the suffix '-able', where 'balance' comes from Old French 'balance' and Late Latin 'bilanx' and '-able' comes from Latin '-abilis' meaning 'able to be'.

'balance' entered Middle English from Old French 'balance' (from Late Latin 'bilanx' or Medieval Latin 'bilancia'), itself built from Latin elements 'bi-' (two) and 'lanx' (plate, scale pan); the adjective-forming suffix '-able' derives from Latin '-abilis' and produced the modern English formation 'balanceable'.

Initially related to the idea of a 'pair of scales' or 'weighing' (the root meaning), the word family evolved to mean 'to make even or steady'; 'balanceable' specifically developed to mean 'able to be balanced', a direct extension of that sense.
