Ka (à¤•) is the first consonant of the Devanagari language. The letter can be traced back to the Brahmi letter (ka). Brahmi script is the oldest writing systems used in South and Central Asia from the 1st millennium BCE. The letter later transformed into the present form of Ka.
The letter is pronounced as [kÉ™] or [k] when appropriate. It is not only in Nepali, Sanskrit of Hindi every other Indic languages have similar sounding letter although it is written in a different script. For example some of the scripts in different languages are:
Conjunction of Ka
When half Ka is used in conjunction with other letters, the shape of the resulting letter is sometimes confusing. Here are some examples:
à¤•à¥ + à¤¤(tÌª) gives us ktÌª with becomes “à¤•à¥à¤¤” but, traditionally it is written in a irregular form as shown below:
à¤•à¥ + à¤·(Ê‚) become a new letter à¤•à¥à¤· (kÊ‚).
à¤™à¥(Å‹) + à¤• can be written as “à¤™à¥à¤•” but, traditionally it is written as a vertical conjuct Å‹k, placing à¤™ above the à¤•.
Similarly, the following conjunctions are also written as vertical conjunct:
à¤•à¥ + à¤–(kÊ°) gives us kkÊ° with the à¤• placed above the à¤–.
à¤•à¥ + à¤²(lÌª) gives us klÌª with the à¤• placed above the à¤².
à¤•à¥ + à¤µ(Ê‹) gives us kÊ‹ with the à¤• placed above the à¤µ.
à¤•à¥ + à¤¨(nÌª) gives us knÌª with the à¤¨ rotated and placed under the hook of the à¤•.
Like all other letters, Ka letter in conjunction with the twelve vowels result in twelve different sounds like ka, kaa, ki, kee, ku, kuu, ke, kai, ko, kau, kam, kah.
