1. Models of Morphology: Three Principal Approaches
In morphological theory, linguists have developed three main models to analyze exactly how words are formed and how their internal structure should be represented. For the UGC NET exam, you must know the formal names and aliases of these frameworks.

🔥 Match the List: Morphological Frameworks
| Model Name | Alias (Mechanism) | Core Concept & Application |
|---|---|---|
| Morpheme-Based | Item-and-Arrangement (IA) | Treats words as linear arrangements of morphemes, like a string of beads. Word formation is putting minimal units together in a fixed order. (Best for Structuralist Linguistics) |
| Lexeme-Based | Item-and-Process (IP) | Focuses on transforming a base lexeme into a new word through operational rules, rather than simple concatenation. (Best for Generative Grammar) |
| Word-Based | Word-and-Paradigm (WP) | Treats the whole word as the central unit of analysis. Morphological relationships are mapped as transformations within paradigms (e.g., run, runs, ran). (Best for Inflectional Analysis) |
2. Inflection: Grammatical Modification
In linguistics, inflection refers to the modification of a word’s form to express grammatical features such as tense, person, number, gender, case, mood, or voice.
Key Rule: Unlike derivation, inflection maintains the word's original grammatical class (a noun stays a noun, a verb stays a verb) and merely adapts its form to the grammatical context of the sentence.
- English Examples: In English, inflection is relatively limited but marks important distinctions. It includes plurals (cat ➡️ cats), possessives (girl ➡️ girl’s), verb tenses (walk ➡️ walked), and comparative forms (big ➡️ bigger).
- Internal Stem Changes: Inflection is not just suffixation; it also involves internal vowel shifts, such as sing ➡️ sang ➡️ sung or goose ➡️ geese.
- Synthetic Languages: While English has lost much of its Old English inflectional system, languages like Latin, Spanish, and German display extensive inflectional paradigms. Typologically, heavily inflecting languages are considered a subtype of synthetic languages.
3. Derivation: Forming New Lexemes
Derivation refers to the active process of forming entirely new words by altering a base form or adding affixes. It is the primary mechanism through which a language's vocabulary expands.
- Changing Categories: Central to word-formation, derivation frequently changes the grammatical category (part of speech) of a word. For example, it converts nouns into adjectives (child ➡️ childish) or verbs into nouns (teach ➡️ teacher).
- Enriching Capacity: Because it creates new dictionary entries (lexemes), derivation fundamentally enriches a language's expressive capacity in a way that inflection does not.
- Varying Definitions:
- In descriptive linguistics, it is the process of affixation to form new words.
- In historical linguistics, derivation denotes the etymology or historical origin of a word.
- In generative grammar, it describes the sequence of abstract, rule-based transformations that generate a syntactic structure.
4. Frequently Asked Questions
What is Item-and-Arrangement (IA) morphology?
IA is a morpheme-based model that views words simply as a linear sequence of morphemes joined together, much like beads on a string (e.g., un + break + able). It is heavily associated with structuralist linguistics.
What is the difference between Inflection and Derivation?
Inflection modifies a word for grammatical reasons (like adding "-ed" for past tense) without changing its part of speech. Derivation creates an entirely new word, often changing the part of speech (like adding "-er" to turn the verb "teach" into the noun "teacher").
What is a paradigm in Word-and-Paradigm (WP) morphology?
A paradigm is the complete set of all grammatical word-forms a single underlying lexeme can take. For example, the paradigm for the verb "WRITE" includes write, writes, wrote, writing, and written.
What are internal stem changes in inflection?
While English usually inflects words by adding suffixes (like -s or -ed), it sometimes inflects by changing the internal vowels of the word itself. Examples include goose becoming geese, or sing becoming sang.
