В чем разница между ordinary и common и usual и not special ?Пожалуйста, приведите примеры.

@Milo_2010 If you want to describe your hotel, you could say:

"A common hotel": it means that the hotel is exactly what you expect from it. It's a good hotel. It has got bedrooms, a hall, things that hotels usually have. It's common. There's nothing especially good or especially bad about it.

"An ordinary hotel/not special hotel": it means that the hotel is basic, it lacks something. It's not necessarily terrible, but there's nothing special about it, nothing that makes it stand out. It's just a basic place.

"An usual hotel": it wouldn't sound very natural to me, I think this word shouldn't be used within this context! :)

I would say that:
"A common hotel" would be an average place (2.5-3 stars)
"An ordinary hotel" would be a little below average place (2.25-2.5 stars)

"Common" sounds slightly better than "ordinary".

Something like this ^^
