It often has a slightly negative connotation, suggesting that something is unfamiliar, overly trendy, or even a bit pretentious.
Here are some examples of how it might be used:
* "I prefer the old-fashioned way of doing things, not these newfangled gadgets."
* "She's always trying out newfangled diets and exercise routines."
* "The restaurant's menu was filled with newfangled dishes I couldn't even pronounce."
Essentially, "newfangled" is a way to express a dislike for something novel or unfamiliar, especially if it seems overly complex or unnecessary.
