词根词缀：-bust, -ust, -bur; bust-, bur-, ur-

【来源及含义】Latin: burere, "to burn up"; from urere, with an inserted or faulty separation of b in amburere, "to burn around"; which stands for amb-urere, "to burn around", but it was misdivided into am-burere and because of this misdivision, the new verb burere was formed with the past participle bustum; so, it really came from urere, "to burn, to singe"
