'autohemorrhage' originates from Greek and New Latin elements: Greek 'autós' meaning 'self' combined with Greek 'haima' meaning 'blood' and the suffix '-rrhagia' meaning 'bursting forth', forming a Modern New Latin/medical English compound.

'auto-' (Greek) was prefixed to the noun 'haemorrhage' (from Latin 'haemorrhagia', from Greek 'haimorrhagia'), producing the compound 'autohemorrhage' in modern medical usage.

Initially the parts meant 'self' and 'bursting forth of blood'; over time the compound has come to mean specifically 'bleeding that occurs spontaneously or from within the body'.
