Is Funner a word? I’ll bet you’ll say it isn’t, but according to Merriam Webster it is! (added about 2010) But is that all we should consider in order to communicate effectively? NO! Effective communication is also about the impression we make on people. Using the word funner makes you sound like a you're *UNedUmaCaTed.* I don't care if the dictionary does say it's a word, if you sound like an idiot you'll be treated that way and all credibility goes out the window. So, funner IS a word, but if you use it, you’ll communicate that you’re not too bright. And if you use the term more funner, they’ll be sure of it!
