Coagulate
/koʊˈæɡjəˌleɪt/
verbB2
Definition
To coagulate means that a liquid changes into a thicker or more solid state, often by clumping together small particles. This usually happens naturally, like when blood forms a clot to stop bleeding, or when milk turns sour and thickens. It can also happen in cooking or science.

To change a liquid into a thick or solid form by clumping particles
- •The blood began to coagulate quickly after the injury.
- •Milk left outside too long can coagulate and spoil.
- •The chef used an enzyme to coagulate the milk and make cheese.
To form clumps or lumps inside a liquid
- •The sauce started to coagulate because it was too hot.
- •Proteins in the egg white coagulate when cooked.
🧲 Make It Stick
- ✓Think of 'coagulate' like 'thicken' (A2 word), but more about liquids becoming solid or clumpy, not just thicker like soup
- ✓Picture red blood slowly forming a jelly-like mass to stop bleeding from a cut
- ✓It's the feeling when milk gets old and changes from smooth liquid to chunky or solid bits
- ✓Sounds like 'CO-ag-u-late' → imagine small drops coming together to make a bigger, thicker drop
- ✓Think of how cheese is made when milk coagulates and turns solid
- ✓NOT like 'freeze' (which makes liquid solid by cold), coagulate is about particles clumping, not temperature only
- ✓NOT like 'evaporate' (liquid turning into gas), coagulate is liquid becoming solid or thick, not disappearing
- ✓NOT like 'dissolve' (solid mixing into liquid), coagulate is the opposite: liquid turning into solid pieces

- •Historical development: Used since the 1600s in medical and scientific contexts to describe blood clotting and liquid thickening
- •Modern usage: Common in medicine (blood coagulation), cooking (cheese making), and science (chemical reactions causing solids to form)
