what is the total number of letters in greek alphabet
Greek alphabet In its classical and modern forms, the alphabet has 24 letters, ordered from alpha to omega. Like Latin and Cyrillic, Greek originally had only a single form of each letter; it developed the letter case distinction between uppercase and lowercase forms in parallel with Latin during the modern era.
Ñ Ñ (lower case ñ, Spanish: eñe, Phonetic Alphabet: /ˈeɲe/ "énye",  pronunciation (help·info)) is a letter of the modern Latin alphabet, formed by placing a tilde (called a virgulilla in Spanish) on top of an upper- or lowercase N.[1] It became part of the Spanish alphabet in the eighteenth century when it was first formally defined, but it is also used in other languages such as Galician, Asturian, the Aragonese Grafía de Uesca, Basque, Chavacano, Filipino, Chamorro, Guarani, Quechua, Mapudungun, Mandinka, and Tetum alphabets, as well as in Latin transliteration of Tocharian and Sanskrit, where it represents [ɲ]. It represents [ŋ] in Crimean Tatar. In Breton and in Rohingya, it denotes nasalization of the preceding vowel.
