Capable of being exceeded or surpassed; possible to go beyond or exceed.
From 'exceed' + '-able' (capable of being). This word emerged naturally as English speakers needed an adjective form to describe things that could be surpassed.
The '-able' suffix is productive in English, meaning we can attach it to almost any verb—'exceedable' means something CAN be exceeded, which is actually rare for many limits we face.
