The following table shows how the consonant ক is written when followed by the vowels.
If one wants to write only the consonant without the inherent vowel, one adds the 'hasanta' mark (্) with the consonant.

In an abugida, when a consonant stands alone, it is pronounced with an inherent vowel. For example, the 'কার' form of আ is called 'আ-কার' (a-kar, /a kar/). This diacritical form is called 'কার' (kar, /kar/) form of the following vowel in Bengali. An abugida differs from an alphabet by the fact that in an abugida, any vowel following a consonant is written as an diacritic appended with the preceding consonant.
