Say that you are 20 years old and I am 70. And I say:
- I am much older than you.
I would like to ask if I can omit 'much' in the sentence. I think it is required because of the age range.
It's not necessary. It is still a fact that if the other person is 20 and you are 70, you are older than him/her. Using "much" adds an extra element.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
