This study investigated the degree of compatibility between grammatical elements and linear sequences of bound morphemes in the Ibibio verbal system. The data for this study were obtained from twelve native speakers of Ibibio using constructed sentences, spontaneous discussions and introspections. The study employed the morpheme-based hypothesis. From findings, this research proposes that the grammatical elements within the Ibibio verbal system are affixed to the main verb. These affixes are arranged in a linear order from left to right. Occurring after the verb root, are bound morphemes to convey negation, reversal and relativization processes. The study examines the arrangement of elements in the verbal structure of the Ibibio language. It notes that this structure typically consists of a certain order: first, a person or agreement marker is used, followed by a modal, tense, aspect, an auxiliary marker, another agreement marker, the main verb, and last, the negative marker, depending on the specific construction. The Ibibio language including Uda spoken in Mbo Local Government Area, Akwa Ibom State belongs to the Lower Cross of the Benue-Congo language phylum, (Essien 1990, Urua 2000, Udosen and Okon, 2019, Akpan and Okon 2020). Every language has rules. This is why it is quite rare to find a language devoid of grammatical rules. Sentences are built with lexical items which belong to different word classes including the verb. The verb is classified as belonging to the open class and accommodating categories within the Ibibio language. It has the potential to be expanded to accommodate further grammatical operations. The verb is a pervasive linguistic element, as it is observed in nearly all human languages. The verb can be referred to as the fundamental component of the grammatical structure of any language, as it serves as the basis for the derivation of other syntactic categories. The verb has garnered significant scholarly interest from numerous researchers.
