I want to know the answer to the following question:
When was Government phonology first seen?
All the background I'm provided with is that "Government phonology, which originated in the early 1980s as an attempt to unify theoretical notions of syntactic and phonological structures, is based on the notion that all languages necessarily follow a small set of principles and vary according to their selection of certain binary parameters.". Is that enough to answer the question?
Answer: yes
