| Citazioni | (69) S → NP⁀VP; VP → V⁀NP; (70) S → {NP, VP}; VP → {V, NP}. In (70), no order is assigned to the elements on the right-hand side of the rule; thus, {NP, VP} = {VP, NP} [...]. Proponents of 'set systems' such as (70) have argued that such systems are more "abstract" than 'concatenation systems' such as (69), and can lead to a study of grammatical relations that is independent of order, this being a phenomenon that belongs only to surface structure. |
