What does haemorrhagic mean?
Haemorrhagic is a formal medical adjective meaning involving or characterized by haemorrhage, especially severe or uncontrolled bleeding. It is used when bleeding itself is the defining feature of a condition, most famously in “haemorrhagic stroke,” where a ruptured blood vessel causes bleeding within the brain. The term is related to but not interchangeable with “haemorrhage”: the latter names the bleeding and can also be a verb, while “haemorrhagic” describes a bleeding condition or its effects. In British English the standard spelling begins haem-; US medical writing commonly uses hemorrh-. Haemorrhagic has a strongly clinical tone and is not the normal word for ordinary cuts or nosebleeds. Its importance lies in identifying conditions in which rapid blood loss or bleeding into an organ affects diagnosis and treatment. The word’s precision also distinguishes a haemorrhagic stroke from an ischaemic stroke, in which a blocked vessel reduces blood flow. Outside medicine, the adjective is occasionally used metaphorically for a disastrous or overwhelming situation, though such usage is much less common than the technical one.

Where does haemorrhagic come from?
Haemorrhagic was formed in English from haemorrhage with the adjectival suffix -ic. Haemorrhage ultimately comes from Greek haimorrhoos or haimorrhagia, based on haima, meaning “blood,” and rrhagia, referring to rupture or bursting. The Greek blood-root also appears in related English words such as haemorrhoid and haemophilia.
