Questions & Answers about गैस चूल्हे पर पानी उबालिए।
A word-by-word breakdown:
- गैस = gas
- चूल्हे = stove, but here it is in a changed form because it comes before a postposition
- पर = on / on top of / over
- पानी = water
- उबालिए = boil (polite command: please boil)
So the structure is:
[place] + पर + [object] + [polite command]
More literally, it is something like:
On the gas stove, boil water.
Because चूल्हा changes to चूल्हे before a postposition like पर.
This is called the oblique form. Many masculine nouns ending in -ा do this:
- लड़का → लड़के
- कमरा → कमरे
- चूल्हा → चूल्हे
So:
- चूल्हा = stove
- चूल्हे पर = on the stove
This is very common in Hindi. If a masculine -ा noun is followed by a postposition such as में, पर, से, को, तक, etc., it usually changes to -े.
