In Spanish, the word “esposas” means both “wives” and “handcuffs.”
Esposas is the feminine plural of esposo, which comes from the Latin sponsus (same root word for “spouse”), which comes from the Latin spondere, which means “to bind,” and note that that’s exactly what handcuffs do.
And mention that wrists in Spanish translates as muñecas, which also means dolls, and that even the Real Academia Española doesn’t know the etymology of the word or why the two words mean the same thing.
On the other hand, only a single guy would ever ask why esposas simultaneously means “handcuffs” and “wives.”
