Severe or original bleeding; a medical condition of excessive hemorrhage or bleeding from a primary source.
From Greek ἄρχο- (árkhō-, 'beginning' or 'primary') combined with -rrhagia (from ῥαγία, rhagia, 'bursting forth' or 'excessive flow'). The -rr- spelling shows Greek influence.
Old medical terminology like this shows how doctors once tried to describe symptoms by location or origin—'archorrhagia' specifically meant bleeding from what they thought was the primary source, not just 'bleeding somewhere.'
