but on the way the word is currently used. precisely. Words morph.

pre vent (aka prevent) from the Latin

prevent (dis-enable)

there is (used to be in the 60s) a Christian prayer that went: prevent us oh Lord

and the vicar had to explain it by emphasising it as pre vent, because the meaning was literally to go before, ie lead, ie enable and encourage. And if you "go before" you can stop things. Etymology is clear, morphing is understandable but it leads to (pre vents?) an antagonymous duality. And is, in the context of the OP, curious.

Now is designer a word that has any meaning worthy of usage? or does it mean expensive &/or cheap?
