[I]n the system employed in this text the periipheral elements are always treated as the determiners and the nuclear ones as the determined, since it is the peripheral constituent which determines the membership of any structural series.

It is possible to employ 'determiner' and 'determined' in another sense. For example, the forms of the stems may be considered determiners of the distribution of the alternants /-əz ~ -z ~ -s/ of the English plural morpheme. Here the stems may be said to be the determinerconstituents and the particular form of the suffix is determined.
