Ñ

Ñ or ñ ( ) is a letter of the extended Latin alphabet, formed by placing a tilde (also referred to as a in Spanish, in order to differentiate it from other diacritics, which are also called ) on top of an upper- or lower-case . The origin dates back to medieval Spanish, when the Latin digraph began to be abbreviated using a single with a roughly wavy line above it, and it eventually became part of the Spanish alphabet in the eighteenth century, when it was first formally defined.
