Input Correspondence Principle #

@cite{ackema-neeleman-2004}

The ICP constrains the phonological realization of affixes: an affix must take as its phonological host the head of the phrase it selects. This means affixes are always linearly adjacent to their syntactic selectee.

Consequences for Modification #

When the attributivizer (Attr) is realized as an affix, the ICP forces it to be adjacent to the adjective head A. This means dependents of A (PPs, CPs, AdvPs) cannot linearly intervene between A and N, because they would separate the affix from its host.

When Attr is a clitic or free word, the ICP does not apply, and dependents may intervene freely.

Affix Continuity Constraint (70) #

For null affixes, the ICP is extended: a null affix Z taking input head Y must form a continuous morphological chain. The Affix Continuity Constraint ensures null affixes behave like overt affixes with respect to adjacency requirements.

When adjacency is imposed, dependents of A cannot intervene between A and the modified N. This is the morphophonological factor of the MAG. Returns true when intervention IS blocked by the ICP.

    Null Attr blocks intervention (Affix Continuity Constraint).

    MAG condition (b) is exactly the negation of ICP adjacency: intervention is licensed when Attr does NOT impose adjacency.
