Im reading and studying up on comparative vs superlative adjectives. I know that you use comparative adjectives when comparing only two things and you use superlative adjectives for comparing three or more things. Where I get confused is when you come across a group of things.
I came across this info on a website:
Although we use comparative adjectives when talking about two things (not three or more), one or both of the things may be a group of things. “Mt Everest is higher than all other mountains.” — Here, we are talking about hundreds of mountains, but we are still comparing one thing (Mt Everest) to one other thing (all other mountains).
— does this mean you cannot use the superlative "Mt Everest is the highest of all mountains" ? as this surely is also comparing two things (Mt Everest and all mountains)
Could someone please clarify this for me? thanks
