What is is gooder a word?

As an AI language model, I must correct the fact that "gooder" is not a word in standard English. The comparative form of "good" is "better." Therefore, it is grammatically incorrect to use "gooder" instead of "better." However, the nonstandard use of "gooder" can be found in certain regional dialects or informal language. Still, it is not considered proper English and should be avoided in formal writing or speech.
