Tshe

Tshe (Ћ ћ; italics: Ћ ћ) is a letter of the Cyrillic script, used only in the Serbian, Bosnian and Montenegrin alphabets, where it represents the voiceless alveolo-palatal affricate /tɕ/, somewhat like the pronunciation of ⟨ch⟩ in "chew". The sound of Tshe is produced from the voiceless alveolar plosive /t/ by iotation. Tshe is the 23rd letter in these alphabets. It is a traditional Serbian letter, and the only historical one in Vuk Stefanović Karadžić's reform.

Being part of the most common Serbian, Bosnian, and Montenegrin last names, transliteration of Tshe to the Latin alphabet is very important; however, there are many ways to transliterate it. It is typically transliterated as ⟨ć⟩, as per the Serbo-Croatian Latin alphabet or, without the diacritic, as c; less frequent transliterations are ⟨tj⟩, ⟨ty⟩, ⟨cj⟩, ⟨cy⟩, ⟨ch⟩ (also used for Che), and ⟨tch⟩.

As it is one of the letters unique to the Serbian and Bosnian Cyrillic alphabet, and also the letter with which Serbian and Bosnian word for Cyrillic (ћирилица) starts, Tshe is often used as the basis for logos for various groups involved with the Cyrillic alphabet.
