quantity sensitivity

In METRICAL PHONOLOGY, a FOOT-shape PARAMETER governing the DISTRIBUTION of light and heavy SYLLABLES in TERMINAL NODES of feet. In quantity-insensitive feet, all syllables are treated as equally light or equally heavy; there are no restrictions. In quantity-sensitive feet, heavy syllables may not occur in RECESSIVE positions, and are STRESSED. Quantity-determined feet are quantity-sensitive, with the additional requirement that dominant terminal nodes must DOMINATE heavy syllables. Quantity sensitivity may also be formalized using MORAS (as in METRICAL GRID theory).
