Third person singular present tense of 'full'; to make full, to fill up, or to perform the fulling process on cloth.
From Old English 'fullian,' meaning to make full or to fill; also used in textile production contexts from Middle English onward.
When you see 'fulls' in old records, you can usually tell if it's someone's job title (a 'fuller') or describing the cloth-making process—context is everything in historical documents.
