Expert writing Tips

Best practice

Avoid using "much more longer". "Longer" is already a comparative adjective, so adding "much more" is redundant. Use "much longer" or "far longer" instead.

Common error

Do not combine comparative forms unnecessarily. Using "much more longer" is a common mistake because it includes both "more" and the -er suffix, which both indicate comparison. Choose one or the other.
