Mudpack → The word is formed from "mud" (from Old English *mudd*, meaning wet earth or soft soil) and "pack" (from Old French *pacquer*, meaning to pack or bundle). A mudpack refers to a treatment involving the application of a mixture of mud or clay, typically for cosmetic purposes, which is packed onto the skin.
Think of 'wet earth' ('mud') being 'packed' ('pack') onto the skin for a treatment. This helps you remember that a mudpack is a cosmetic application of mud.
