Stress subordination principle
PHONOLOGY: a universal convention proposed by Chomsky & Halle (1968) in the linear analysis of stress assignment. In this analysis stress assignment rules assign the feature [1stress] to vowels. The operation of subsequent stress rules is subject to stress lowering in the following way (Chomsky & Halle (1968:17)):
When primary stress is placed in a certain position then all other stresses in the string under consideration at that point are automatically weakened by one.EXAMPLE: Consider the assignment of stress in the compound black-board. The main stress rule applies in a cyclic fashion (see cyclic domain), reassigning [1stress]; the previously assigned [1stress] is weakened to [2stress] by stress lowering:
1 1 1 2 black + board black board
