Is it proper to use “more sweeter” when comparing two things or is it “more sweet”? I.E. This pie is more sweeter than the other one. If you can, please explain why one is incorrect.
Hi Chadwick
I don’t consider it at all debatable that this is grammatically wrong: [color=red]This pie is more sweeter than the other one. :shock:
You cannot use both the word ‘more’ and the -er ending at the same time to make an adjective comparative.
You usually add -er to one-syllable adjectives to compare two things:
[color=blue]This pie is sweeter than the other one.
[color=blue]His car was cheaper than mine.
Sometimes people use ‘more’ with one-syllable words, so you could look at ‘more sweet’ as an optional form of the comparative. (But, as I’ve already mentioned, simply adding -er to the end of the word is the usual way to make a one-syllable adjective comparative.)
You use ‘more’ instead of the -er ending with some two-syllable adjectives, and for all adjectives with three or more syllables:
[color=blue]This pie is more delicious than the other one.
[color=blue]My car was more expensive than his.
.
Maybe you want to say “much sweeter”. More sweeter is incorrect. 
Finally! Thank you for proving that I was correct
