These papers treat The Cambridge Grammar of the English Language as a working grammar: strong enough to build on, explicit enough to test, and detailed enough that local revisions matter. Some directly correct CGEL analyses. Some extend CGEL machinery into areas where the book is suggestive but not fully worked out. Some belong to the same post-CGEL tradition of category/function cleanup.
Divergence note: many departures from CGEL are practical treebanking decisions, such as exhaustive closed-class lists, explicit unary nodes, punctuation and error conventions, generic Coordination labels, and drawing supplements into ordinary trees. Others are substantive analyses or corrections, including complex numerals as syntactic structures, coordinates as headed, some pre-head nominal dependents as modifiers rather than complements, relative clauses as gap constructions, and treating some CGEL comparative and ellipsis gaps as heuristic rather than syntactic.
arXivThese are not corrections to CGEL itself. They apply CGEL-style distinctions to dictionaries, pedagogical grammar, or later category claims.
