Questions & Answers about ज़हर बच्चे से दूर रखिए।
Because से is a postposition, and nouns usually switch to the oblique form before a postposition.
- basic form: बच्चा = child
- oblique singular: बच्चे
- so: बच्चे से = from the child
This is very common in Hindi:
- लड़का → लड़के से
- कमरा → कमरे में
- बच्चा → बच्चे से
So बच्चे here is not the plain plural children. It is the singular oblique form of बच्चा.
Here से means from.
In this sentence, it marks separation or distance:
- बच्चे से दूर = away from the child
This use is very common with words like दूर:
- घर से दूर = far from home
- आग से दूर = away from fire
- बच्चे से दूर = away from the child
So से is not doing something complicated here; it is simply showing what something should be kept away from.
