An open letter from a group of academics to Michael Gove, the Education Secretary, won the inaugural Bad Grammar Award, sponsored by the Idler Academy, last week. The judges objected to a number of phrases in the letter, including "demands too much too young", on the grounds that 'young' can't be an adverb. I must say that the phrase doesn't sound too bad to me -- I am probably remembering the 1979 Specials song, Too Much Too Young. Perhaps that influenced the writers of the letter, too. It's a lot more catchy than the version suggested by Nevile Gwynne, one of the judges - 'demands too much when children are too young to be ready for so much'.
Runners-up were Tesco for "for using adjectives as nouns and failing to put hyphens in the right place", and London Transport for "mixing gerunds and infinitives on a safety sign".
I have looked in vain for the actual examples of these crimes on the Idler website (here - it's interesting and worth a look), so I can't repeat them. Nor, are they in the Guardian article, where I got the rest of my information from.
Actually, there are no set rules for hyphenation in English, and it is notoriously difficult to specify what part of speech some words are, so the judges' were merely expressing their opinion.
Here's the story.
