Able to be forgiven; worthy of forgiveness or pardon; not so serious that it cannot be excused.
From 'forgive' (Old English 'forgiefan,' combining 'for-' and 'giefan' meaning to give) plus '-able' suffix (capable of being). This means literally 'capable of being forgiven.'
What makes something 'forgivable' versus 'unforgivable' is deeply human and varies by culture and relationship. A lie told to protect someone's feelings might be forgivable, while the same lie for selfish gain might not be—the intention matters as much as the action.
