As a nonnative English speaker, sometimes I struggle with usage of 's or of or nouns together, for example
- Ali's car.
- the pole of the flag ,
- the walls of the train.
- the beauty of women's
I don't know if it's OK if I change them, especially when, for exam[;e, I'm writing and I think if I change them in the sentence it would be more effective, and I write like this:
- flag's pole or flag pole
- train walls
- the beauty of a woman or the beauty of theirs.
