(personal pronoun)transposition [Lat. transponere ‘to moveacross’]1 In word formation, a change in word class as new expressions are formed throughsuffixation: read (=verb), readable (=adjective), reader (=noun). ( alsomodification)2 metathesistree-adjoining grammar (abbrev. TAG)A mildly context-sensitive extension ( mildly context-sensitive language, contextsensitivegrammar) of context-free (CF) grammar, including operations which adjointrees in a recursive way ( recursiveness) (see diagram above).TAG is distinguished among grammar models in being essentially tree-based, and hasbeen explored both as a formalization of transformational grammar (Kroch and Joshi)and as an alternative grammar model (Abeille). There exist lexicalized unification-based( unification grammar) and stochastic ( stochastic grammar) variants. TAG isespecially popular in computational linguistics.ReferencesAbeille, A. 1991.
