is now spelt as ñ. The word tilde comes from Spanish, derived by metathesis of the word título as tidlo, this originally from Latin TITVLVS "title" or "heading"; compare cabildo with Latin CAPITULUM. From spellings of anno abbreviated as año, as explained above, the tilde was thenceforth transferred to the n and kept as a useful expedient to indicate the new palatal nasal sound that Spanish had developed in that position: año. The sign was also adopted for the same palatal nasal in all other cases, even when it did not derive from an original nn, as in leña (from Latin ligna) or señor (from Latin SENIOR). Other Romance languages have different spellings for this sound: Italian and French use gn, a consonant cluster that had evolved from Latin, whereas Occitan and Portuguese chose nh and Catalan ny even though these digraphs had no etymological precedent. When Morse code was extended to cover languages other than English, a sequence ( — — · — — ) was allotted for this character. Although ñ is used by other languages whose spellings were influenced by Spanish, it has recently been chosen to represent the identity of the Spanish language, especially as a result of the battle against its obliteration from computer keyboards by an English-led industry. Cross-linguistic usage In Spanish it represents a palatal nasal. This is also the case of Philippine languages, Aymara, Quechua, Mapudungún, Guarani, Basque, Chamorro, Leonese, Yavapai, and Iñupiaq, whose orthographies have some basis in that of Spanish. Many languages of Senegal also use it in the same way. Senegal is unique among countries of West Africa in using this letter. It also represents a palatal nasal in Galician and Uruguayan Portuguese. In Tetum, it was adopted to represent the same sound in Portuguese loanwords represented by nh, although this is also used in Tetum, as is ny, influenced by Indonesian. In Tagalog, Visayan, and other Philippine languages, most Spanish terms that include ñ are respelled with ny. The conventional exceptions (with considerable variations) are proper names, which usually retain ñ and their original Spanish or Hispanicised spelling (Santo Niño, Parañaque, Mañalac, Malacañan). It is collated as the 15th letter of the Filipino alphabet. In old Filipino orthography, the letter was also used, along with g, to represent the velar nasal sound (except at the end of a word, when ng would be used) if appropriate instead of
