I find etymology and linguistics fascinating, primarily because it provides subtle details and delineation on words. Which leads to increased quality and quantity of communication. A great example of this effect is the delineation of “envy” and “covet”.
Envy – to want something you could have, example: someone else’s possessions, stuff, or vehicles
Covet – to want something you can’t have, example: someone else’s attributes, luck, or spouse
Now both aren’t necessarily good. In fact, generally speaking both are normally bad. But the detail here is useful in terms of psychology and mindset. Normally in the recent past, it was more typical to “envy” someone else’s wealth, because it was understood that it was more or less attainable (maybe not to the same level, but attainable none the less). That wealth was something one could have if they developed the goal, and worked to achieve it.
However in the present, I find that the majority of America is starting shift towards “coveting” wealth, because they literally don’t even believe they can have it outside of being lucky alone! Again, I’m not proposing that envy is healthy either, but the sheer frequency that most people believe they can’t possess or build wealth is increasing disturbingly quickly.
Action: use care regarding what words you use and how you use them, as it reflects your mindset!
