2006I've just come back from nine days of holiday (or holidays?). It's one holiday. "...from a nine-day holiday." is best.
I've just come back from a nine-day holiday. (Can we say 'a nine days holiday' no or 'my nine days holiday' no or 'my nine days' holiday'? no)
Could I ask native speakers to help me please? Thank you in advance.
