“dissolution,” “decomposition,” “disintegration,” “loosening” — Noun-forming compound suffix — “process of dissolution, decomposition, or disintegration of (a named substance or structure)”
The word entered English in the 1820s as lysis (noun), borrowed from Modern Latin lysis, from Greek λύσις (lysis) — literally “a loosening” or “a dissolution” (from lyein “to loose, to untie, to release”). The adjective lytic appeared in the 1830s, and hemolysis in the 1900s. The root lyein (“to loose, to dissolve”) connects -lysis to the entire dissolution and decomposition roots: hemolysis (hemo- + lysis → dissolution of red blood cells), thrombolysis (thrombo- + lysis → dissolution of a blood clot), and autolysis (auto- + lysis → self-dissolution or self-destruction of tissue). The noun-forming compound suffix-lysis is extremely productive across all medical specialties: e.g., hemolysis, thrombolysis, autolysis, cell lysis, and lysis.
