Ka (Devanagari)

Ka (क k) (कवर्ण ) is the first consonant of the Devanagari abugida. It ultimately arose from the Brahmi letter 𑀓, after having gone through the Gupta letter. Letters that derive from it are the Gujarati letter ક, and the Modi letter 𑘎.

Usage
In all languages, क is pronounced as or  when appropriate. In the following example, क implements its inherent vowel, the schwa:
 * नकली = nakali "fake"

In this example, क deletes the inherent schwa for correct pronunciation:
 * बकवास = bakvās "nonsense"



Certain words that have been borrowed from Persian and Arabic implement the nukta to more properly approximate the original word. It is then transliterated as a q.
 * क़दम = qadam "footstep"
