IPA: /ˈmʌdfloʊ/
KK: /mʌdfloʊ/
A type of natural disaster where a large amount of wet earth and debris flows down a slope, often caused by heavy rain or melting snow.
The heavy rain caused a mudflow that swept through the village, damaging homes and roads.
Mudflow is formed from "mud" (from Old English *mudd*, meaning wet earth or soft soil) and "flow" (from Old English *flowan*, meaning to flow or run). The word describes the movement of wet earth or soil that flows down a slope.
Think of 'wet earth' ('mud') that 'flows' ('flow') down a slope — that's what a mudflow is.
