Whilst we're on the subject - /ure/. I can't even work out what sound it is!!! The thing on phonics play says its an unusual sound not used in most accents. I think it might be a northern thing - my mother in law says 'poor' as 'poo-er' and moor as 'moo-er'., whereas I'd say them the same as paw and more. So I'm thinking us Southerners don't need to teach this phoneme at all?
