Llave — Clef

The Latin words that began with “cl” changed, pretty consistently, to “ll” as Latin changed into Spanish.

Today’s example of this: the Latin word for “key” was clavis. This became the modern Spanish word for “key”, llave.

There are, however, a few interesting other descendants of clavis, and thus distant relatives of llave. They include:

• the Spanish clavo, meaning, “nail”. It’s a more educated word, coming to Spanish via Latin scholars later on, so it didn’t lose the natural cl- sound the way the traditional words did.
• English words like clef and enclave. Yes, in music you talk about the “key” and the “clef” and they come from the same word originally!
