What does fuller mean?
A fuller is historically a craftsman who practised fulling, the essential final stage in making woollen cloth. Freshly woven wool was greasy, uneven, and loosely woven; the fuller cleaned it by washing and pounding it in water — often with fuller's earth, an absorbent clay, or with urine rich in ammonia — causing the fibres to mat together so the cloth became denser, thicker, and stronger. In medieval England, where wool was the backbone of the economy, fullers were numerous and organised into their own guilds, and from the Middle Ages onward the water-powered fulling mill mechanised their laborious work. Though the independent trade has all but vanished, the term endures in textile history, in the absorbent clay known as fuller's earth, and in the widespread English surname Fuller. Separately, 'fuller' also appears routinely as the comparative form of the adjective 'full', describing something more complete or comprehensive.

The fuller's secret ingredient was stale urine — its ammonia made it the best degreaser available for washing wool until modern chemistry came along.

Etymology of fuller
The word fuller descends from the Old English and medieval craft of fulling cloth; the occupation itself is ancient, known across medieval Europe and long before. The English term is tied to the verb 'full', from Germanic origins, meaning to tread or beat cloth. The related material 'fuller's earth' takes its name directly from the trade, having been prized since antiquity for absorbing grease from wool. The surname Fuller, borne by figures such as architect R. Buckminster Fuller and theologian Thomas Fuller, arose from this occupational origin, following the common medieval pattern by which trades gave families their lasting names.
