ah but burned and burnt have different meanings to me:
burned - the actual burning of something - 'I've burned the cake'
burnt - the item itself - 'the cakes are burnt'
that is just to me though...
hmmm I thought of the American/English divide but a couple of the novels were American and I know both spellings whereas most of my spellings (which are correct all you American people - our dictionary was published first!

) are only the English...we stil have
felt and
built so I wondered if it was just a shift to the
d sound and away from the
t sound...hmmm I do believe more brainwork (at least I do!) is needed...
