Cluster is an external or internal Merge of more phrases than one in an argument structure at a vP-phase, making their G(oal)/H(ead)-features (fs) form a set of G/H-features. In a multiple WH-question, Cluster order is WPagr WPadj (WPadj…) at a vP-phase. And in a coordinate structure, any phrase may not be moved out of feature-clustered conjuncts. An associate NP feature-clusters to an expletive (EXPL) there, and a nominal that-clause feature-clusters to an EXPL it in an argument structure at a vP-phase, the EXPL there/it forming a complete set of ϕ-fs and a Case-feature. A feature-clustered EXPL there can move to the Spec-Tcomp for simultaneous Agree, but a feature-transferred associate NP cannot possibly move there. And a feature-clustered EXPL it may stay in situ for covert Agree (CA) at a vP-phase or move to the Spec-Tcomp for overt Agree (OA) at a CP-phase. This paper argues that Cluster may be one of economic principles, and that only a feature-clustered EXPL can merge internally with a probe (P) for simultaneous Agree in narrow syntax (NS).
