Morphology

Rosetta + Stone

This is a proper-name metaphor deriving from a specific historical artifact (the Rosetta Stone) whose role as a ‘key’ to decipherment must be known to understand the figurative meaning. Knowing the literal words 'Rosetta' and 'stone' does not enable a B1 learner to infer 'key to understanding a complex subject', so the expression is idiomatic and not compositionally predictable.

Etymology

Rosetta Stone is also used for anything that gives a clear key to a hard problem. The real Rosetta Stone helped scholars match three texts and 'unlock' the meaning of ancient writing, so people call a helpful tool or document a 'Rosetta Stone' when it makes something difficult to 'understand'.
