While speaking any language the pronunciations can be slightly different than bookish/written language. We tend to use the short form of verbs or words.
e.g. in English

He will – He’ ll
I had – I’d etc.

The short forms change as per the region, community and educational level of the speaker. There are many dialects i.e बोली भाषाएं in Marathi.
Here we are considering short forms used in the spoken language of standard Marathi.

1) In present continuous tense आहे (Ahe) or its forms are generally pronounced as ‘य’ (y) along with main verb

e.g.

मी करतो आहे (mI karato Ahe) -> मी करतोय (mI karatoy)
here करतो आहे is changed to करतो + य i.e. करतोय (karatoy)

2) In neuter gender words ending ए (e) is pronounced as अं (Am)

e.g.

“Leaf” in Marathi is “पान “(pAn). Its plural is “पाने”(pAne).
While speaking, “पाने”(pAne) is pronounced as पानं(pAnM)
The last न(n) with a dot on it is pronounced as nasal sound/elongated vowel.

3) If subject or object according to which the form of verb is created, is of neuter gender, then ending with ए (e) is pronounced as अं (Am).

The way of pronunciation is same as we seen in the second rule.
Let’s see its applicability.
e.g. That tree moves -> ते झाड हलते (te jhAD halate)
Here, the object is “झाड” (jhAD) which is nuter gender.
So verb हलते (halate) can be pronounced as हलतं (halataM)

This rule is applicable only when subject or object according to which verb is formed, is of neuter gender. Not otherwise.

All the above rules are explained with more examples in the corresponding lesson of “Learn Marathi from English” blog at
