Hi there,

I just want to make sure that I understood the differences between a lexical, morphological and semantic mistakes correctly. If am not mistaken semantic mistakes deal with problems concerning meanings, for example writing a sentence that is correct grammar wise but doesn't make any sense is a semantic mistake, morphological mistakes deals more or less on how the word should look like, for example childrenS is a morphological mistake, so that leaves lexical mistakes, what are those exactly??

can someone sum up the differences between those 3 mistakes please so that I may know for sure that I got them down correctly?

Thank you in advance
