Capable of being gained, earned, acquired, or obtained through effort or action.
From Middle English 'gain' (from Old Norse 'gagn' meaning benefit or profit) combined with the suffix '-able' (from Latin '-abilis' meaning capable of). The form suggests something is within reach or achievable.
The fact that we have a word 'gainable' reveals how English-speaking cultures have historically thought about achievement and reward—if it's 'gainable,' it implies that effort and merit can actually get you somewhere.
