It is formed from Latin N with the addition of a caron (háček in Czech and mäkčeň in Slovak) and follows plain N in the alphabet.
[1][2] In Czech and Slovak, ň represents /ɲ/, the palatal nasal, similar to the sound in English canyon.
Thus, it has the same function as Albanian, Macedonian and Serbo-Croatian nj / њ, French and Italian gn, Catalan and Hungarian ny, Polish ń, Occitan and Portuguese nh, Galician and Spanish ñ, Latvian and Livonian ņ and Belarusian, Russian, Rusyn and Ukrainian нь.
In Russian, Ukrainian and similar languages, soft vowels (е, и, ё, ю, я) also change previous н to нь in pronunciation.
In Turkmen, ň represents the sound /ŋ/, the velar nasal, as in English thing.
