Possessor noun phrases take the form of a prepositional phrase with the preposition də, which, in addition to its possessor-marking function, is a generic relator allowing the modification of a nominal head by another NP (e.g. garaf də beer [bottle of beer] 'beer bottle').
The typical position of posessor noun phrases is postnominal (i.e. after the possessum). Occasionally, however, possessor NPs (i.e. də-PPs) are placed in prenominal position, which is usually reserved for pronominal possessors. All NPs occurring in this position are rather short (typically containing no more than two words), which suggests the constraints on these occurrences must be sensitive to heaviness.
