The word 'well-floured' is a modern English compound adjective formed by combining the intensifying adverb 'well' with the noun 'flour' and the adjectival suffix '-ed'. Its logic is transparent and descriptive: it literally means "having been provided with flour in a good or sufficient manner." The core component, 'flour', has an elegant history, deriving from the Latin flōs (flower), as it was metaphorically considered the "flower" or finest part of the ground meal. This compound follows a productive English pattern (e.g., well-dressed, well-informed) to efficiently describe a state optimal for a specific purpose, such as preparing a surface for baking to prevent sticking.

Structure: well (sufficiently) + flour (powdery grain substance) + ed (adjective suffix) - well: From Old English wel, meaning "in a good way, satisfactorily, abundantly." In this compound, it functions as an intensifying adverb meaning "sufficiently" or "properly." - flour: From Old French flour, flor ("flower, finest part"), from Latin flōrem (accusative of flōs), meaning "flower." It came to mean the fine, powdery substance produced by grinding grain. In this word, it is the core noun root. - ed: A Middle English suffix from Old English -ed, -od, used to form adjectives from nouns, indicating "having the quality of" or "provided with."
