The title of this article looks strange. But as you will read it you will see that it is not strange rather you have already learned it.
Recall the article about adjectives. There we had said that if the masculine-singular form of adjective ends with आ(A) then there will be different forms of adjective depending on gender and multiplicity. E,g, काळा/ काळी /काळे, etc.

Similarly in the article about “To want” we saw that different forms of हवा ( havA) are used depending on gender and multiplicity of the object. E.g हवा / हवी / हवे etc.

I think by now you must have found out that these forms follow a specific pattern. I call it “आ-ई-ए-ए-या-ई rule”
i.e if masculine-singular form ends with आ(A) and words have different form as per gender-multiplicity then ending will be :

masculine singular    आ (A)
feminine singular       ई (I)
neuter singular           ए (e)
masculine plural         ए (e)
feminine plural           या (yA)
neuter plural               ई (I)

When you will observe below table you will understand it clearly and will also realize that in many articles wherever we had mentioned such forms, they were actually following this rule. So you do not need to learn them by heart. You can create a different form of words your self

1: When applying this rule ending with consonant स(s), we use श(sh) instead of स(s) for :
feminine singular
feminine plural
neuter plural

So forms for कसा (kasA) are:
कसा-कशी-कसे-कसे-कश्या-कशी (kasA-kashI-kase-kase-kashyA-kashI)

2: As you know letters च(ch), ज(j), झ(jh) have two pronunciation in Marathi.
One is lighter and the other is heavier.
When applying this rule to words ending with consonant च(ch), ज(j), झ(jh), the heavier sound is used for:
feminine singular
feminine plural
neuter plural
