Front page news: the Oxford Etymologist harrows an international brothel
Why brothel? We will begin with the customer. Broþel surfaced in Middle English and meant “a worthless person; prostitute.” The letters –el are a dead or, to use a technical term, unproductive suffix, but even in the days of its efflorescence it was rarely used to form so-called nomina agentis (agent nouns), the way –er is today added to read and work and yields reader and worker.
