Related link: My answer to One answer to a Q. is suited to ELL, but the other answer is suited to EL&U on ELU Meta.
In the course of an argument, Rathony said the following:
I would answer, if you ask me, that ELU is closer to a little more smart and sophisticated question forum and ELL is a little less sophisticated question forum. The difference is not so big.--Rathony
I then corrected him:
'ELU is closer to a little more smart and sophisticated question forum and ELL is a little less sophisticated question forum. The difference is not so big.' Correct usage would be "ELU is a slightly smarter (note correct comparative) and more sophisticated question forum, and ELL is a slightly less sophisticated question forum. The difference is not very big OR the difference is not so great." Even this could be bettered by "ELU is a forum for slightly smarter and more sophisticated questions" etc. You have some work to do on comparatives and so forth before you offer advice to native speakers.--Me.
A native would never be confused between more smart and smarter and insist on using "is a slightly smarter and more sophisticated". That proves you are not a native.--Rathony AND: At least I know how to use the comparative when two adjectives are used at the same time. You don't.--Rathony
Give me a reference that justifies your usage.--Me.
No. I don't want to help you. You find it yourself.--Rathony.
I've tried. I can't. So can someone find a reference that justifies his idea that the construction 'more smart' can be used instead of 'smarter' where more than one adjective is involved?
