I'm not terribly familiar with the syntax of PPs, but I've noticed that a handful of them do not seem to satisfy any constituency tests, particularly 'than'. 'Than' is listed in dictionaries as both 'preposition' and 'conjunction'. The former is likely referring to cases where 'than' precedes - and, supposedly, governs - an NP. For example:
- *Than the ant, the elephant is larger.
- What is the elephant larger than? ?Than the ant.
- *Than what is the elephant larger?
- *It is than the ant that the elephant is larger.
- I can't think of any word that can substitute 'than + NP'.
Moreover, 'than' may precede clauses as well:
- He's better than you think.
- I've eaten more salt than you've eaten rice. (OK, this is a joke translation of a Cantonese phrase.)
That raises the question of whether it constitutes a coordinating conjunction or a subordinating conjunction (which, depending on the conjunction, are subsumed under prepositions and complementisers in modern times). Since '*Than you think, he's better.' is not grammatical, the prepositional analysis seems unlikely (compare as long as, because). While this doesn't undermine its preposition status when preceding NPs, it seems to make it even less likely now.
Coordinating conjunction actually seems possible. We say 'He is tired but happy' and 'He is more tired than happy'. We say 'He looks confident and you think he is (confident)', and likewise we can say 'He looks more confident than you think he is (confident)'.
The other alternative is that 'than' is a complementiser, but that cannot capture the cases where 'than' precedes an NP. Besides, that would imply constituency, which again seems not to be satisfied (e.g. *than I have, John has eaten more.)
My questions are:
- Is there any good way to defend the constituent status of than-phrases?
- If not, have there been any alternative accounts in the literature? Could 'than' be a coordinator?
Thanks.
