brick: [15] For what is today such a common phenomenon, the word brick made a surprisingly late entry into the English language. But of course until the later Middle Ages, bricks were very little used in Britain. It was not until the mid-15th century that they were introduced by Flemish builders, and they appear to have brought the word, Middle Dutch bricke, with them. The ultimate source of the word is not clear, although some have tried to link it with break. [brick etymology, brick origin, 英语词源]
