Historically, ⟨ñ⟩ arose as a ligature of ⟨nn⟩; the tilde was shorthand for the second ⟨n⟩, written over the first; [2] compare umlaut, of analogous origin. It is a letter in the Spanish alphabet that is used for many words—for example, the Spanish word año "year" ( ⟨anno⟩ in Old Spanish) derived from Latin: annus. Other languages used the macron over an ⟨n⟩ or ⟨m⟩ to indicate simple doubling. The set of all natural numbers is standardly denoted N or N . {\displaystyle \mathbb {N} .} [3] [29] Older texts have occasionally employed J as the symbol for this set. [30] This article is about "positive integers" and "non-negative integers". For all the numbers ..., −2, −1, 0, 1, 2, ..., see Integer. 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 mathematics, the italic form n is a particularly common symbol for a variable quantity which represents a natural number. The set of natural numbers is referred to as N . \mathbb {N} .

Including0 is now the common convention among set theorists [24] and logicians. [25] Other mathematicians also include0, [i] and computer languages often start from zero when enumerating items like loop counters and string- or array-elements. [26] [27] On the other hand, many mathematicians have kept the older tradition to take1 to be the first natural number. [28] Notation [ edit ] It is used in a number of English terms of Spanish origin, such as jalapeño, piña colada, piñata, and El Niño. The Spanish word cañón, however, became naturalized as canyon. Until the middle of the 20th century, adapting it as nn was more common in English, as in the phrase " Battle of Corunna" [ citation needed]. Now, it is almost always left unmodified. The Society for the Advancement of Spanish Letters in the Anglo Americas (SASLAA) is the preeminent organization focused on promoting the permanent adoption of ⟨ñ⟩ into the English language.

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).N with descender Small letter n with mid-height left hook was used by the British and Foreign Bible Society in the early 20th century for romanization of the Malayalam language. [13] Set-theoretical definitions of natural numbers were initiated by Frege. He initially defined a natural number as the class of all sets that are in one-to-one correspondence with a particular set. However, this definition turned out to lead to paradoxes, including Russell's paradox. To avoid such paradoxes, the formalism was modified so that a natural number is defined as a particular set, and any set that can be put into one-to-one correspondence with that set is said to have that number of elements.

Ruppel, Klaas; Aalto, Tero; Everson, Michael (2009-01-27). "L2/09-028: Proposal to encode additional characters for the Uralic Phonetic Alphabet" (PDF). 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.
