Ah, the ever-evolving English language. And all of the other languages, too. Constantly in motion, that's language for you. What is a perfectly serviceable word at one time (like, "behoof") falls by the wayside and we're left with "benefit, advantage." (Obviously, those are also perfectly serviceable, but they don't have the same sudden start, followed by an exhale you can draw out like a vuvuzela call.)
"Nice" used to mean fastidious.
"Plight" went from "to pledge" to "an unfavourable condition or state."
You can plain over about change and how fair the old days were, but my rede is to go with the flow, but also throw in an occasional old-timey word on a freak. (I've been known to be a scapegrace betimes.)
Enjoy the latest episode from the H.A.B.I.T. crew! (It's back on the Welcome Page. We're working on that.)
