Cloak-and-dagger is an idiom that is several hundred years old. We will examine the definition of the phrase cloak-and-dagger, where it came from and some examples of its use in sentences.

Cloak-and-dagger describes an activity or operation that involves espionage, mystery or secrecy. Originally, cloak-and-dagger was a French term, de cape et d’épée, and also a Spanish term, de capa y espada, both of which translate literally as cape and sword. These phrases came from a type of dramatic play that was popular in these countries in the eighteenth century. In these dramas, a character often concealed his identity and his weapon behind a cloak. Note that the term cloak-and-dagger is properly rendered as hyphenated, according to the Oxford English Dictionary, as it is an adjective used before a noun. However, the term is sometimes seen without hyphens, as in cloak and dagger.
