Nothing could be clearer
Is your resume “clearer” after editing it, or is it “more clear”? Based on some of the resumes we see in the staffing business, neither comes into play. According to various reputable sites, both forms are considered acceptable, but “clearer” is technically correct.
Why? Because there are specific rules for constructing comparatives in English. Generally speaking, comparatives of single-syllable words are formed by adding an -er to the end of them. Hence, “small” is “smaller” (not “more small”) and “tall” is “taller” (not “more tall”). Since “ugly” has two syllables, “more ugly” is preferred over “uglier,” but both are perfectly acceptable, and that’s the ugly truth.
It’s comparatives of multiple syllable words that you attach the a “more” to, as in, more angry, more annoying.
Given that it’s English we’re talking about, there are exceptions. The comparative of “fun,” for example, is not “funner,” but “more fun.”
Hopefully, that’s clear enough for you. So forget the nonsense we shoveled your way about “specific rules.”
