"Preppier" Natural Recordings by Native Speakers
"Preppier" is not a widely recognized word in the English language. However, I think you may be looking for the word "preppier" as a comparative form of the word "preppy", which refers to something or someone that is related to the "preppy" lifestyle, style or culture, often associated with wealthy, well-educated, and fashion-conscious individuals, typically in a suburban or town setting.
If this is not the correct word, please let me know and I can try to provide another possible explanation.
A person who prepares for and often obsessively stocks up on supplies in anticipation of potential disasters, shortages, or catastrophic events, such as natural disasters, economic collapse, or widespread social unrest.
