'She was sitting with her hands/palms on the ground, at either of her sides.'

Does this sound correct/natural?

 

[emsr2d2]

No.

She was sitting with a palm on the ground on each side [of her body].

 

[99bottles]

No.

She was sitting with a palm on the ground on each side [of her body].

Wait, I thought 'on the side of sth' means literally on that sth whereas 'at/by the side of sth' means next to it. Have I got it wrong?

 

[emsr2d2]

Wait, I thought 'on the side of [STRIKE]sth[/STRIKE] something' means literally on that [STRIKE]sth[/STRIKE] something whereas 'at/by the side of [STRIKE]sth[/STRIKE] something' means next to it. Have I got it wrong?

If you're looking at that as an absolute rule then yes, you've got it wrong.

I was standing on her left-hand side = I was standing to her left.
There's a mark on the side of your face = The mark is actually on the surface of your face.

I was standing on her left-hand side = I was standing to her left.

Regarding this sentence, is it wrong to say, 'I was standing at her left side'?

 

[emsr2d2]

It's not grammatically wrong but it wouldn't be what I would use.
