full v.
"to tread or beat cloth to cleanse or thicken it," late 14c., from Old French foler, fouler "trample on, press," from Latin fullo "fuller, launderer," also a kind of beetle, a word of unknown etymology. Perhaps the Middle English word was from Old English agent-noun fullere, which probably was formed from Latin fullo with a native ending.
