Definition
The word *dicky* is informal and has a few different meanings, often depending on context. It can refer to something that is unreliable or in poor condition; think of a *dicky* knee that might give out at any moment. In British English, it can also mean 'ill' or 'unwell'. Another (archaic) meaning refers to a detachable shirt front, like a bib. Due to its informality, it is less commonly used in formal settings.
