E fit be 1 - 20 sentences. Context: <response>: For one course for LSA summer institute for 1991, Alan Prince and Paul Smolensky come up with optimality theory - one overall architecture for phonology wey talk say languages dey choose how to pronounce word wey go best satisfy list of constraints wey dey arranged by importance; if one constraint wey dey lower rank dey violated, e fit be say e dey necessary to obey one wey dey higher rank. John McCarthy and Alan Prince come extend the approach to morphology, and e don become one dominant trend for phonology. The appeal to phonetic grounding of constraints and representational elements (e.g. features) for different approaches don dey criticized by supporters of 'substance-free phonology', especially Mark Hale and Charles Reiss.
