Reconsidering Linearity: Evidence from CV Metathesis

(1) S1 is consistent with the precedence structure of S2, and vice versa (No Metathesis). Let x, y ∈ S1 and x′, y′ ∈ S2. If x x′ and y y′, then x precedes (<) y iff x′ precedes (<) y′. • In other words, if a segment precedes another in the input, that precedence relation should be preserved by the corresponding segments in the output.3 • How many such relations exist in a word? • For a word of length n, there are (n2 − n)/2 pairs of segments with this precedence relation. • Example: The underlying form of hypothetical salofidu / / has eight segments, and 28 precedence relations.
