It provides a systematic way of explaining how sentences are formed, how structures are related, and how meaning is conveyed through syntax. For learners of linguistics, especially those working with African language data, this framework offers powerful tools to analyse sentence structures and uncover the principles that govern language use. By beginning with this foundation, you will be well prepared to engage with more advanced syntactic theories later in the course.

LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS The aim of this Series is to introduce you to the fundamental concepts of transformational generative grammar and to equip you with the skills needed to apply these concepts to linguistic data, particularly from African languages. We shall commence this Series by exploring the background and development of transformational generative grammar, including its core concepts and vocabulary. Next, we will examine the principles of transformational grammar, focusing on deep and surface structures, as well as transformations and rules. Following that, we will move on to practical applications, where you will analyse sentence structures and transformations using African language data. Finally, we will wrap up by considering critical perspectives, discussing both the strengths and limitations of transformational grammar as a framework. Series Learning Outcomes Upon completing this Series, you should be able to: • SLO 1.1 define the core concepts and vocabulary of transformational generative grammar, • SLO 1.2 explain the historical background and development of transformational generative grammar, • SLO 1.3 describe the distinction between deep structure and surface structure, • SLO 1.4 demonstrate how transformations and rules operate within sentence structures, • SLO 1.5 apply transformational grammar principles to African language data through practical exercises, and • SLO 1.6 evaluate the strengths and limitations of transformational generative grammar as a syntactic framework. 1.1 Introduction To Transformational Generative Grammar 1.1.1 Historical background and development Transformational generative grammar is a theory of syntax developed by Noam Chomsky in the mid-twentieth century. It revolutionised linguistics by proposing that language is not simply a collection of memorised sentences but rather a system governed by rules that generate an infinite number of possible sentences. This framework introduced the idea that grammar is a mental system, reflecting the innate capacity of humans to produce and understand language. Fill in the blank: Transformational generative grammar proposes that language is governed by ______ that generate an infinite number of sentences.

One of these is competence, defined as the speaker’s internal knowledge of language, contrasted with performance, which refers to actual language use in communication. Another key concept is generativity, the ability of grammar to produce an unlimited number of sentences from a finite set of rules. The framework also distinguishes between deep structure, which represents the underlying syntactic relations, and surface structure, which reflects the actual spoken or written form. Fill in the blank: The distinction between competence and performance highlights the difference between internal knowledge and actual ______ use. Box 1.1: Key concepts in transformational generative grammar Pilot questions 1.1 1. Who developed transformational generative grammar? 2. What does transformational generative grammar propose about language? 3. Define competence in the context of transformational generative grammar. 4. What is the difference between deep structure and surface structure?

What does generativity mean in transformational grammar? 1.2 Principles Of Transformational Grammar 1.2.1 Deep structure and surface structure One of the most important principles in transformational grammar is the distinction between deep structure and surface structure. Deep structure refers to the underlying syntactic representation of a sentence, which captures the essential grammatical relationships between words. Surface structure, on the other hand, is the actual form of the sentence as spoken or written. Transformations are the rules that map deep structures onto surface structures, allowing us to explain how different sentence forms can express the same meaning. Fill in the blank: Transformations are the rules that map ______ structures onto surface structures. Figure 1.2: Relationship between deep and surface structures 1.2.2 Transformations and rules Transformations are operations that modify sentence structures, such as moving, deleting, or inserting elements. For example, the transformation from a declarative sentence to a question involves moving the auxiliary verb to the front. These rules explain how sentences with different forms can be derived from the same deep structure. Transformational grammar therefore provides a systematic way of accounting for sentence variation while maintaining grammatical consistency. Fill in the blank: The transformation from a declarative sentence to a question involves moving the ______ verb to the front. Transformation Type Original (Deep/Source) Transformed (Surface) Declarative → Interrogative "She is reading a book." "Is she reading a book?"

"The student was praised by the teacher." Affirmative → Negative "They will attend." "They will not attend." Box 1.2: Examples of transformations in English Pilot questions 1.2 1. What is the difference between deep structure and surface structure? 2. What do transformations in grammar achieve? 3. Give one example of a transformation from declarative to interrogative. 4. Which verb is moved to the front in forming a question? 5. How does transformational grammar explain sentence variation? 1.3 Applications To African Language Data 1.3.1 Illustrative exercises with sentence structures Transformational grammar is not only a theoretical framework but also a practical tool for analysing real language data. When applied to African languages, it helps to reveal how sentence structures are organised and how transformations operate across different linguistic systems. For example, many African languages use subject–verb–object (SVO) order, but transformations such as passivisation or question formation may alter this order while maintaining grammaticality. By working through exercises, you will see how transformational rules apply to specific sentence structures and how they highlight the underlying deep structures. Fill in the blank: Transformational grammar helps reveal how sentence structures are organised and how ______ operate across different linguistic systems.

(The book was seen) Swahili Mtoto anasoma kitabu (The child is reading a book) Je, mtoto anasoma kitabu? (Is the child reading a book?) Kitabu kinasomwa na mtoto (The book is being read by the child) Table 1.1: Sample sentence transformations in African languages 1.3.2 Practical analysis of transformations In practice, applying transformational grammar to African language data involves identifying the deep structure of a sentence and then showing how transformations produce different surface forms. For instance, in Yoruba, the passive construction highlights the object by moving it to the subject position. Similarly, in Swahili, interrogative forms are created by adding a question marker at the beginning of the sentence. These analyses demonstrate how transformational grammar provides a systematic way of explaining variation while respecting the unique features of each language. Fill in the blank: In Yoruba, the passive construction highlights the object by moving it to the ______ position.
