What distinguishes constraint ranking in Optimality Theory from rule-ordered derivation in generative phonology when analyzing phonological alternations?

💡 Explanation

Constraint ranking in Optimality Theory differs from rule-ordered derivation, because it employs ranked, violable constraints rather than strict, exceptionless rules. Consequently, certain constraints can be violated to satisfy higher-ranked constraints; therefore, the output reflects constraint interaction, rather than serial rule application.
