I surrender!
Is usa(d)ge a British spelling? In our unabridged dictionary, I found no alternate spelling for "usage."
I know that we Yanks have our own spelling for some words, stemming from our desire to separate ourselve from the mother country. Perhaps this is one of them.

I think it was a play on a typo in the subject of your original post where you accidentally spellled usage u-s-a-d-g-e.
I checked a few sources and found no such word as "usadge".
Also I found no such word as "spellled".
The irony of it all!My fourth grade teacher told me my spelling would come back to haunt me. Mrs. Williams, where ever you are, I was not worthy! :)
'Usadge' is certainly not a British spelling. I'd assumed all along that the original entry was a typo and people hadn't bothered to correct this in their reply.
