Morphology

bad + penny

Although a learner who knows 'bad' and 'penny' can tell it refers to something negative and a coin, those constituents do not signal the key meaning of repeated, unwelcome return. The phrase is proverbially idiomatic ('a bad penny always turns up') and the recurrence/personification sense cannot be predictably derived from the literal words, so a B1 learner would not reliably infer the full meaning.

Etymology

Bad penny comes from a time when a damaged or fake coin was called a bad penny and people tried to avoid it, but the coin still kept turning up in pockets and at shops. So, like that coin, a 'bad penny' today means someone or something 'unwanted' that keeps coming back.
