IPA: /ˈblɒkɪdʒ/
KK: /ˈblɑkɪdʒ/
A situation where something is blocked or stopped, preventing movement or progress.
The doctor found a blockage in the patient's artery that needed to be treated.
Blockage → It is formed from "block" (from Old French *bloquer*, meaning to obstruct or stop) and "-age" (a suffix indicating an action or result). The word "blockage" refers to the result of blocking or the state of being obstructed.
Think of something that is 'stopped' or 'obstructed' — 'block' means to stop, and '-age' indicates the result of that action.
