Free Morphemes

Free morphemes apparently differ from bound morphemes in that they occupy syntactic positions. However, this assumption is not a conclusive one. There is no reason, for example, to assume that English articles and demonstrative pronouns occupy syntactic positions, since they are always occupy NP initial position, the initial-external periperal clitic position according to Anderson's General Theory of Affixation. It would seem to be difficult to define auxiliaries in these terms of clitic positions because they move to initial position in questions. However, they only occur in VP initial position in IE languages and move to sentence initial position inquestions. All these positions are projected by Anderson's theory.
