I would like to know the semantic difference between the constructions hotel's room and "a hotel room".
Other examples:
- He spent the night in a hospital bed / a hospital's bed
- He fell over a bike stand / a bike's stand.
I would like to know the semantic difference between the constructions hotel's room and "a hotel room".
Other examples:
Your examples use nouns that are used to modify other nouns (attributive nouns). Possessive (also called Saxon Genitive) constructions, on the other hand, show possession [in the extended (my bike's front wheel) rather than just the proprietorial (John's bike) sense].
"a hotel's room" - a room belonging to a hotel
"a hotel room" - a specific type of room, somehow related to hotels (in this case also usually belonging to the hotel but that is not necessarily important)
similarly "hospital's bed", vs "hospital bed"
"the bike's stand" would imply that the stand belongs to the bike while "bike stand" describes a type of stand that is somehow related to bikes (of course, here, designed to house bikes).
