Question

Comparative form of 'simple' => 'simpler' or 'more simple'
I have seen both versions from my colleagues. Which one is correct? If both are correct, what different in their meaning?

Thank you in advance.

Answer

Both are acceptable - "simpler" is slightly preferable.
One syllable:
fat,fatter,fattest
Two syllables:
simple, simpler / more simple, simplest / most simple
Three or more syllables:
comfortable, more comfortable, most comfortable

Answer

Personally I would use "simple = simpler" all the time.

I have never heard that explanation before though fdmaxey and looking at it now it makes perfect sense!  Thank you - I may just use it with my students!
