The English-speaking world particularly has adopted them. (Three Times Three Equals Twelve)
Can I say: The English-speaking world has particularly adopted them?
I need native speakers' help.
No, that would change the meaning. You need "particularly" to be in a position where it clearly refers to "The English-speaking world", not to "has adopted them".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
