Which is correct - to talk of someone's 'teenage sister' or her 'teenaged sister'? Googling the phrases reveals fairly equal distributions of both, on sites from both sides of the Atlantic. I notice the BBC tend to say 'teenage', though my guess had been that 'teenaged' was more 'correct'. Should I go with the Beeb (my usual model for all things grammar and spelling)?

I've started seeing 'teenaged' popping up more often, but 'teenage' is how i've always written and said it.
I think I missed the memo when it did the rounds.

- it could just be something to do with tense.
'of teenage'
'is teenaged'
'are teenagers'

Fowler says 'teenage' is adjective and noun and 'teenaged' is adjective, so I guess either is okay.

Great - thanks - I knew you'd know. I think I'll go with 'teenage' 'cos it sounds more natural.

So, who's the teenage sister, Rosy, and - more to the point - i thought you were on a break?
