What does congelation mean?
Congelation is the process by which a liquid becomes solid through exposure to cold — in ordinary terms, freezing. The word carries a formal, even slightly antique tone: where modern English would say a pond froze or milk solidified, an older or more literary register speaks of their congelation. Historically the term had a wider scientific reach. Early physicians used it for the clotting of blood, and it appeared in discussions of chemistry and natural philosophy to describe any transition from fluid to firm, coherent matter under cold. Today congelation survives chiefly in scholarly, technical, and historical writing, lending precision and gravity to descriptions of ice, frost, and other effects of severe cold. Its Latin pedigree — descending from congelare, "to freeze together" — links it to relatives such as congeal, gelid, and gelatin, all built on the same root meaning cold-induced stiffness. For writers seeking an elevated alternative to "freezing," congelation offers both precision and a touch of classical dignity.
The process or result of a liquid becoming solid through cold; freezing.
"The congelation of the river made the millrace silent for the season."
Formal register; largely displaced by "freezing" in contemporary usage.
The coagulation of blood, or the hardening of body tissues caused by intense cold.
"Seventeenth-century physicians debated whether congelation of the blood occurred at death."
Found mainly in historical medical texts.
Rarely used in the plural; the uncountable form is standard when referring to the process generally.
"The treatise catalogued the various congelations observed in alpine lakes."
"Congelation" was once the scientific term of choice for freezing — before "freezing" itself got cool enough to take over.

Etymology of congelation
Congelation derives from the Latin congelatio, formed from congelare, meaning "to freeze together," itself a combination of com- ("together") and gelare ("to freeze"), from gelu ("frost"). English adopted the word from Old French congelation in the late Middle Ages, with attested use by the early 15th century. It shares its root with congeal, gelid, and gelatin.
How congelation is actually used
"Congelation" is formal and somewhat archaic in everyday use; modern writing typically prefers "freezing" or "solidification." It survives mainly in scientific, historical, and literary contexts.
Easily confused with congelation
Coagulation is the thickening or clotting of a liquid (especially blood) into a semisolid state, whereas congelation specifically denotes hardening into a solid through freezing by cold.
