Editing Determiner phrase (section)

===Position===

The fact that determiners typically introduce the phrases in which they appear is also viewed as support for the DP-analysis. One points to the fact that when more than one attributive adjective appears, their order is somewhat flexible, e.g. ''an old friendly dog'' vs. ''a friendly old dog''. The position of the determiner, in contrast, is fixed; it has to introduce the phrase, e.g. ''*friendly an old dog'', ''*old friendly a dog'', etc. The fact that the determiner's position at the left-most periphery of the phrase is set is taken as an indication that it is the head of the phrase. The reasoning assumes that the architecture of phrases is robust if the position of the head is fixed. The flexibility of order for attributive adjectives is taken as evidence that they are indeed dependents of the noun.
