Noon, like other Senegalese languages, gives the possibility of extensive and varied combinations within its large graphic representation (ñ, ŋ). Twin consonants are possible within words between vowels and are noted by two identical letters, such as ɓɓ, cc, ff, hh, kk, ll, mm, nn, pp, ss, tt, ww, yy. However, this excludes the consonants b, d, g, j, ɗ, ƴ, ñ, and those that are pre-nasalized occlusives. Additionally, the "ɗ" letter does not exist in a word as well as in final voiced stops using the letters b, d, g and j. Also, in Noon, a long vowel is represented by a digraph that is considered a letter, while a geminate consonant is interpreted as a series of two identical letters.
