Can I say " my arms skin were scorched by the sun " to mean the same thing ?
I've only heard "I got a sunburn" or "I got a sunburn on my back" or some expression such as that.
A colleague once mentioned that it wasn't until his second year of university, in a morphology class in which he was analysing compound words, that he noticed to his embarrassement and shame that a word he had always know as [sum]burn was not spelled 'someburn':
:D I've got a sunburn on my back.
:( I've got a sumburn on my back.
:D I've got some burn on my back.
:( I've got a someburn on my back.
I see, and discuss something :). Not discuss about :P. But it seems that even people know it, they can't help making the same mistake. If I am not wrong, it will be universally accepted in the future because it is an incorrigible mistake :P like an automatic pilot in speech.
