sometimes to inject a bit of variety in the typical statements, because there seems to be a collection of key words not commonly used by average people that are actually very average themselves. For example, it seems like every third statement or review uses some form of the word "imbue"
a quick glance over here
would suggest much more accurate and often reader-friendly words such as
bathe, diffuse, impregnate, inculcate, infuse, ingrain, instill (oh that's a good one), permeate, etc.....
In grad school, someone had a running list (from crits) of words that were used/abused/over-used, often for the sake of sounding "arty". Too bad I"m such a poor record keeper. Finding that list would be fun.
