in the syntactic hierarchy, which means that semantic dependency is entirely independent of the syntactic dependencies. Morphological dependencies Morphological dependencies obtain between words or parts of words. When a given word or part of a word influences the form of another word, then the latter is morphologically dependent on the former. Agreement and concord are therefore manifestations of morphological dependencies. Like semantic dependencies, morphological dependencies can overlap with and point in the same direction as syntactic dependencies, overlap with and point in the opposite direction of syntactic dependencies, or be entirely independent of syntactic dependencies. The arrows are now used to indicate morphological dependencies. The plural houses in (a) demands the plural of the demonstrative determiner, hence these appears, not this, which means there is a morphological dependency that points down the hierarchy from houses to these. The situation is reversed in (b), where the singular subject Sam demands the appearance of the agreement suffix -s on the finite verb works, which means there is a morphological dependency pointing up the hierarchy from Sam to works. The type of determiner in the German examples (c) and (d) influences the inflectional suffix that appears on the adjective alt. When the indefinite article ein is used, the strong masculine ending -er appears on the adjective. When the definite article der is used, in contrast, the weak ending -e appears on the adjective. Thus since the choice of determiner impacts the morphological form of the adjective, there is a morphological dependency pointing from the determiner to the adjective, whereby this morphological dependency is entirely independent of the syntactic dependencies. Consider further the following French sentences: The masculine subject le chien in (a) demands the masculine form of the predicative adjective blanc, whereas the feminine subject la maison demands the feminine form of this adjective. A morphological dependency that is entirely independent of the syntactic dependencies therefore points again across the syntactic hierarchy. Morphological dependencies play an important role in typological studies. Languages are classified as mostly head-marking (Sam work-s) or mostly dependent-marking (these houses), whereby most if not all languages contain at least some minor measure of both head and dependent marking. Prosodic dependencies Prosodic dependencies are acknowledged in order to accommodate the behavior of clitics. A clitic is a syntactically autonomous element that is prosodically dependent on a host. A clitic is therefore integrated into the prosody of its host, meaning that
