The word "gooder" is actually not widely recognized as a standalone word in English with its own etymology. It is often considered a non-standard or informal variation of the word "better". Nonetheless, "better" comes from the Old English word "betera", which can be traced back to the Proto-Germanic word "*batizô". This term ultimately derives from the Proto-Indo-European root "*bhad-", meaning "good" or "fortunate". Over time, "better" evolved as a comparative form of "good" and has become firmly established in the English language, while "gooder" remains relatively less recognized.
