Ka (क) is the fifth consonant of the Devanagari abugida, used for writing several Indo‑Aryan languages, most prominently Hindi, Sanskrit, Marathi, Nepali, and many others. It represents the voiceless velar plosive /k/ (as in English “skill”) and, when combined with various vowel signs (matras), forms a large set of syllabic characters.
Etymology and Historical Development
- The glyph derives from the Brahmi letter 𐌀 (ka), which itself traces back to the Aramaic kaph and ultimately to the Phoenician kaf (the ancestor of Greek κ and Latin C).
- In the Gupta script (4th–6th c. CE) the form evolved into a more rounded shape, which later standardized into the modern Devanagari क during the 10th–12th centuries.
