Abstract:
The verb phrase (VP) layer is the domain of clausal event and the argument structure of the verb.
Extant works on Urhobo, an Edoid language, have listed lexical and phrasal categories and types 
of sentences in the language with little attention given to the verbs and VPs, which are germane 
to the understanding of Urhobo sentences. This study was, therefore, designed to investigate the 
Urhobo verb phrase layer, with a view to identifying the types of Urhobo verbs, their properties, 
and the derivation of Urhobo VPs.
The split VP hypothesis of Noam Chomsky’s Minimalist Program was adopted as framework. 
The ethnographic design was used. Ughelli North Local Government Area, where Agbarho, the 
standard form of Urhobo is predominantly spoken, was purposively selected. Ten resident native 
speakers, one each from Uvwiamuge, Oviri, Oghara, Orhokpokpo, Ohrerhe, Ophori, 
Ekrerhavwe, Ikweghwu, Ughwrughelli and Okan were selected. They were selected based on 
their proficiency in the language. Primary data were elicited through the Ibadan 400 Wordlist 
and 10 structured interviews, while secondary data were gathered from existing texts in the 
language such as the Urhobo Bible and two Urhobo dictionaries. Data were subjected to 
interlinear glossing and qualitative analyses. 
Syntactic, semantic and morphological criteria were deployed in identifying Urhobo verbs. The 
syntactic criteria produced seven types of verbs: symmetrical, serial, transitive, intransitive, 
Inherent Complement Verbs (ICVs), causative and double object verbs. The semantic criteria 
yielded two types of verbs: echo and ICVs. Complex, causative and splitting verbs were the 
three types identified using morphological criteria. In symmetrical verbs, it is possible to swap 
subjects and objects without a change in meaning; serial verbs share subject and object 
determiner phrases (DPs); transitive verbs obligatorily take object DPs, while intransitive verbs 
do not. Double object verbs must take two object DPs, whereas causative verbs have a causer 
and a causee in a construction. Echo verbs, which are verbs that occur twice in a sentence, are 
also evident in Urhobo. The ICVs obligatorily select specific complements which determine their 
semantic interpretation. A complex verb has an obligatory internal structure that combines a verb 
and a noun, while a splitting verb shares object in intermediate position. In the derivation of the 
Urhobo verb phrase layer, the lexical verb merges with a DP to form a VP, the VP merges with a 
light verb to form a light verb bar (vI
), and the light verb probes its complement domain in search 
of DPs with matching interpretable phi features to value the unvalued features. The case feature 
of the DP is valued as a reflex. Thereafter, the subject DP is externally merged with vI
to form 
light verb phrase in order to satisfy the edge feature of the light verb thus yielding the light verb 
phrase. 
The Urhobo verb types, differentiated by syntactic, semantic and morphological criteria, revealed 
how these verb phrases are arranged.
