Capable of being affected, influenced, or moved emotionally.
From 'affect' (Latin 'afficere'—to influence, move) + '-able' (capable of). The root 'afficere' combines 'ad-' (to) + 'facere' (to do, make), literally meaning 'to do to' or 'to influence.'
Every person is 'affectable'—it's the basic human capacity to be moved, changed, or touched by experiences. Shakespeare would have recognized this word instantly, though we usually say 'influenced' or 'emotional' today.
