Separate Dimensions Associated with Functional Head

This study investigates the concept of Separate Dimensions (SD) as discussed in Chomsky (2021), focusing on their nature, generation, and compatibility with the Strong Minimalist Thesis (SMT) and Computational Efficiency (CE). It addresses how asymmetric syntactic complexes can optimally integrate into the primary workspace. The working hypothesis proposes that Head mediates between primary workspace operations and SD creation. The paper analyzes the combination of syntactic objects with SDs generated by Heads and examines the principles linking SDs back to the main workspace. Building on Chomsky’s (2019b) concepts of disjunction and conjunction, disjunction is treated as Head-Adjunction and NP formation through adjectival modification within one SD. Conjunction (n ≥ 2) includes multiple adjectives modifying a noun with referential similarity, as well as relative clauses linking to the stem structure. The analysis follows criteria for computational legitimacy, no violation of the NTC (No Tampering Condition) or ICC (Inclusiveness Condition), valid SD generation, and specific stem-structure linkage. Head-Adjunction is analyzed as the stage where √Root is placed in the workspace. Disjunction (n=1, single SD) examines noun phrases modified by adjectives and verb phrases modified by adverbs. Conjunction analyzes noun phrases modified by multiple adjectival phrases and relative clauses having a separate dimension through adverbial modification, aiming to elucidate the stages of full sentence formation.
