IPA: /ˌpɜːrkəˈleɪʃən/
KK: /pɜr.kəˈleɪ.ʃən/
The process of a liquid slowly passing through a material that has small holes, allowing it to filter or seep through.
The percolation of water through the soil is essential for plant growth.
Percolation → It is formed from "per-" (meaning through) and "colāre" (meaning to strain or filter). The word describes the process of a liquid passing through a filter or porous substance.
Think of a liquid moving 'through' ('per-') a filter to 'strain' ('colāre') impurities — that's how percolation works.
