Ka (К к or K k; italics: К к or K k or
К к or K k; italics: К к or K k) is a letter of the Cyrillic script.It commonly represents the voiceless velar plosive /k/, like the pronunciation of ⟨k⟩ in "king" or "kick".
The Cyrillic letter Ka was derived from the Greek letter Kappa (Κ κ).
In the Early Cyrillic alphabet its name was (kako), meaning "as".[1]
In the Cyrillic numeral system, Ka had a value of 20.
The Cyrillic letter Ka looks very similar, and corresponds to the Latin letter K. In many fonts, Cyrillic Ka is differentiated from its Latin and Greek counterparts by drawing one or both of its diagonal spurs with curved instead of straight. Also in some fonts the lowercase form of Ka has the vertical bar elongated above x-height, resembling the Latin lowercase k.
In Russian, the letter Ka represents the plain voiceless velar plosive pronounced as //k// or the palatalized one pronounced as //kʲ//; for example, the word короткий ("short") contains both the kinds: pronounced as /[kɐˈrotkʲɪj]/. The palatalized variant is pronounced when the following letter in the word is ь, е, ё, и, ю, or я. In Macedonian and Serbian it always represents the sound pronounced as //k//.
