'Ka' (К, к) is a letter in the
Cyrillic alphabet. It is derived from the Greek letter
kappa (Κ, κ). It looks very similar, and corresponds to the Latin letter
K but, as with most Cyrillic letters, the lowercase form is simply a smaller version of the uppercase. It represents , a
voiceless velar plosive except when followed by ''ь'' or any of the
palatalizing vowels, such as in кедр, ('cedar' in Russian).
