'the Cliffs of Moher'
'the Holy Roman Empire'
What are these? (and was is their relation to the above?)
'the mighty Mississippi'
'the daunting Cliffs of Moher'
'the peaceful Netherlands'
'the majestic Rockies'
'the desolate Outback'
'the evil Holy Roman Empire'
'the setting Sun'
'the massive Parthenon'
[Aren't they just like 'the table' and 'the brown table'? ]
I think there is a dilemma here: (1) if you treat 'the Parthenon' as a name, then you must give 'the massive Parthenon' a disjoint treatment where 'Parthenon' is a common noun, but then you must allow dropping the 'massive' to get 'the Parthenon' where 'Parthenon' is still a common noun. Thus, 'the Parthenon' is ambiguous between the name and the definite description. This is unappealing. (2) if you concede that 'the Parthenon' is not a name, then either the Parthenon does not have a name (in English) or its name is 'Parthenon' and names can have determiners in front (then there is no reason not to think that 'two David Kaplans', 'every David Kaplan', are somehow to get a different treatment than names in argument position).
So the dilemma is this if the expressions on the first list are names, then the expressions on the second list, force one to the distasteful position that expressions like 'the Mississippi' and 'the Netherlands' are lexically ambiguous. If, instead, the expressions on the first list are not names, then there are a few options. (i) 'the Netherlands' is not a name [= BAD], (ii) 'Netherlands' is a name but interacts with determiners, modifiers, quantifiers, etc. [= names are general terms].
No doubt there are some places to explore in there but these look like the main roads.
