In a previous post, I explained that Latin’s long nn turned into the ñ sound of Spanish, which resembles the ni in onion. For example, Latin annus “year” became Spanish año. This development is also the source of the letter ñ itself. The squiggly tilde ~ over the n started as a shorthand form of the letter n, so that ñ stood for a double n, i.e. n over n. Once the symbol was established, it came to be used for instances of the ñ sound that had other origins, including:
- n before i or e (Hispania > España, aranea > araña “spider”)
- n after g (signalis > señal “sign”)
- mn (damnum > daño “harm”)
The ñ was already in use by medieval times. In fact, you can see it in the earliest known example of written Spanish, a 14th-century transcription (in Spain’s Biblioteca Nacional) of the oral epic poem El Cid. In the excerpt above, from the first page of the poem, there’s a visible tilde in the word señor, the third word in the last line.
