I’m culling books because I plan to move one of these days–and there’s so much to get rid of! So, I’m reading books–and in some cases skimming them–to see if they’re worth keeping and moving. Anyway, I came across a book–otherwise well written–that reminded me of how frequently Over and Out are misused in books, TV shows, etc.
Over–when using a radio or whatever–means: It’s your turn to talk (Over to you). Out means: We’re done. (I’m outta here.) Over and out therefore would be silly and impossible. So stop doing that! (It’s another case of mistakes being perpetuated.)
