A. I was very comfortable speaking to everyone.
B. I was very comfortable to speak to everyone.
Why don't we use B? Don't we use adjectives + to ? If so, why not using infinitive in front of "comfortable" ?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
The same az B, for example. You said it's wrong! I got it.
What are the other expressions ( or adjectives ) that follow gerund and not infinitive?
