In Indefinite articles^x, Hyphens^x

Yes. Many would prefer a hyphen: a half-hour, probably because the indefinite article is normally after half: half an hour.CB

Hi,I think I have seen more than enough cases where what people call a verbal noun has the indefinite article 'a' in front of it and at the very least, the sheer number (should it be - sheer numbrs??) of it warrants some good explanations from experts in this forum. I think I can laid out...

I agree with pieanne on the hyphen. The possessive in the second one is awfully strange to me. Where did you come across (not 'come over') that? As for omitting the indefinite article: offer an example where you think it might be unnecessary.
