 
 <prompt> Wetin no dey carry first: constraint wey dey low rank or constraint wey dey high rank? Based on di question wey dey above, write one context wey get di answer. E fit be 1 - 20 sentences. Context: <response>: For one course for LSA summer institute for 1991, Alan Prince and Paul Smolensky develop optimality theory - one overall architecture for phonology according to which languages dey choose pronunciation of word wey dey best satisfy list of constraints wey dey ordered by importance; a constraint wey dey lower rank fit dey violated when the violation na necessary in order to obey constraint wey dey higher rank. The approach soon extend reach morphology by John McCarthy and Alan Prince, and e don become dominant trend for phonology. The appeal to phonetic grounding of constraints and representational elements (e.g. features) for various approaches don dey criticized by proponents of 'substance-free phonology', especially Mark Hale and Charles Reiss.
