Is there such a word ‘luggages’, or is it just ‘luggage’ even if we have more than one piece of it?
‘Luggage’ is a collective noun that refers to all the stuff you’re carrying with you on your trip. So, be it one bag or a few, it’s all called ‘luggage’.
And yes there is such a word as ‘luggages’, even though it might seem redundant. Imagine that there are two groups of tourists in the hotel lobby waiting for their buses to the airport. You’d presumably have two separate areas where their luggages (that belong to either group) are all ready to be loaded onto the buses.
