DS7 too. He hasn't done a language achievement but his science teacher, just for laughs, asked for random list of scientific words last week. He outspelt me blush! I did teach him phonics though - he started off as a whole word reader at 2 (self taught), complained that he couldn't read new words at 5yo so I did a whirlwind phonics course with him over a few weeks, and read and spelt very well thereafter. For what it's worth, his teacher thinks he's spelling partially from whole word memory because some of the words are just not phonetically decodable.
