"Pre-"

I've just heard that the cheeky Greek Prince Phil is being treated for a "pre-existing" heart condition. Well I think that's ugly English. I think that the "pre" could usefully be dropped. He's being treated for an existing heart condition, not one that's just come on. Seems OK to me. I get fed up of being invited to "pre-order" this, that or the other, or to "pre-book" tickets for some event or other. I can just order or book, can't I? I note also that second-hand cars (a useful and honest expression) are now "pre-owned," or, even worse, "pre-loved" (shall we clench buttocks in unison?)

Anyway, must dash. I have to have a pre-look at the schedules to see what time the big match is on tonight...
