In this article we present the precise positions of XP and the finite verb moving to the functional categories in the Old English (OE) main clauses in association with the label algorithm advocated in Chomsky 2013. With V2 and V3 phenomena in Old English the previous studies did not show any consistent accounts on the moved positions of XP and the finite verb mingled with the status of OE pronouns in the main clauses. In the previous studies some proposed IP-V2 and others did CP-V2 in conjunction with the different status (clitic, weak pronoun or Agr clitic) of the OE Pronouns. In contrast we show a consistent account that XP moves to CP Spec and the finite verb moves to C in the OE V2 contexts including wh-clauses whereas XP moves to IP in the V3 clauses due to the label algorithm where the ϕ-feature of C and T makes two lexical items share prominent features in order to complete the labeling of CP and TP respectively.
