Morphology
hemarthrosis = arthrosis (opaque) = hem + arthr + osis
The prefix 'hem-' refers to blood, but the medical context and specific meaning are not easily inferred by learners.
Etymology
Hemarthrosis comes from parts meaning 'blood' (hem-), 'joint' (arthr-) and 'a condition' (-osis). So hemarthrosis literally means 'blood in a joint' and is used for bleeding inside a joint that causes pain and swelling. You can see the same arthr- part in arthritis, which helps to remember the 'joint' part.
