antibody against blood-cell clumping

Etymology
Etymology Information

'antihemagglutinin' originates from modern English, specifically a compound of the prefix 'anti-' (from Greek, meaning 'against') and 'hemagglutinin' (from Greek 'haima' meaning 'blood' + Latin 'gluten' meaning 'glue,' via the formation 'glutinin' for substances causing clumping).

Historical Evolution

'hemagglutinin' was formed in biomedical usage in the late 19th to early 20th century (compare German 'Hämagglutinin'); combining with the productive English prefix 'anti-' produced 'antihemagglutinin' to denote antibodies opposing that activity.

Meaning Changes

Initially, the root referred to a substance that caused blood cells to clump; over time 'antihemagglutinin' has come to mean specifically antibodies or agents that neutralize or inhibit such clumping, a usage stable in immunology.
