IPA: /ˈliːtʃeɪt/
KK: /ˈliːtʃeɪt/
A liquid that has passed through a material and dissolved some of its substances, often containing harmful chemicals.
The leachate from the landfill was tested for pollutants before being released into the environment.
Leachate is formed from "leach" (from Old English *leccan*, meaning to dissolve or drain) and the suffix "-ate" (indicating a process or result). The word refers to the liquid that has percolated through a solid and extracted soluble constituents from it, typically in the context of waste management.
Think of the process of 'draining' ('leach') to remember that 'leachate' is the liquid that results from this process.
