(7) Grammatical Structure

Phrase: A phrase is a group of words without finite verb; which means that a phrase can contain non-finite or infinitive verb.

Types of non-finite verb are infinitive (to sing, to dance, to buy, etc); gerund (singing, dancing, buying, etc)

Kinds of Phrase and Their Grammatical Functions

1. Noun Phrase: it performs the functions of noun such as subject of verb (To cry aloud is a crime), object of verb (They climb the tree), complement of a verb (Richard is the senior boy), apposition of a noun (Joy, the hostess, entered the cabin), object of a preposition (he thought about travelling abroad). 

2. Adjectival Phrase: it qualifies a noun or pronoun (The girl with chocolate teeth kissed me).

3. Adverbial Phrase: it modifies a verb, adjective or another adverb. We have adverbial phrase of time (I saw the boy during the break time), adverbial phrase of reason (he cried in the face of frustration), adverbial phrase of place (the baby is sleeping in the room), adverbial phrase of purpose (Bayo worked in order to succeed), adverbial phrase of result (having left the room, I locked the door), adverbial phrase of condition (to pass the exam, the student must prepare well), adverbial phrase of concession (although fierce in outlook, Mr. Olaniran is kind).

Clause: a clause is a group of words which often has a subject, a finite verb and forms a single part of a sentence. Clause can either be main clause or subordinate clause. The main clause is the main point in the sentence and it can stand alone while subordinate clause relies on main clause to make complete sense.

Kinds of Clause and Their Grammatical Functions

1. Noun Clause: it performs the functions of noun such as subject of verb (what you told us is true), object of verb (kola said he would travel), complement of verb (the principal’s decision was that the senior should stay), apposition to noun (the assumption that students fail English Language is logical), object of preposition (Tolu thought about how he would travel abroad).

2. Adjectival Clause: it qualifies a noun or pronoun it immediately follows (this is the dog that bit her).

3. Adverbial Clause: it modifies a verb, adjective or another adverb in a sentence. Adverbial clause of time (I saw him when he came in), adverbial clause of condition (the boy will not sleep unless you feed him), adverbial clause of reason (the teacher failed because she was not serious), adverbial clause of purpose (Obi went to school in order that he might acquire formal education), adverbial clause of place (Americans can stay wherever they like), adverbial clause of manner (he talked as if he sponsored my education), adverbial clause of result (she cried that she could not close her eyes), adverbial clause of concession (although she studied hard, she failed Chemistry).
