Turkish 'evlerinde' (in their houses) breaks into ev+ler+in+de, each morpheme expressing exactly one grammatical category. Latin -ae simultaneously encodes feminine gender, singular number, and genitive case in one opaque ending. This contrast illustrates:
ATurkish is agglutinative (one morpheme, one meaning); Latin is fusional (multiple meanings per morpheme)
BTurkish is fusional because its morphemes fuse into a single word; Latin is agglutinative because -ae is short
CBoth languages are fusional, but Turkish is less extreme because its words are longer
DTurkish uses derivational morphology; Latin uses inflectional morphology
Agglutinative languages stack transparent, separable morphemes where each encodes a single category — Turkish is the textbook example. Fusional languages compress multiple grammatical categories into single affixes that cannot be cleanly segmented — Latin -ae is the textbook counterexample. Length of the word form is irrelevant to this distinction.
Question 2 Multiple Choice
Which of the following pairs shows an inflectional relationship rather than a derivational one?
A'runs' and 'ran' — both are forms of the verb 'run,' same lexical category, different tense
B'run' and 'runner' — 'runner' is derived from 'run' by adding -er
C'teach' and 'teacher' — the suffix -er creates a new noun from a verb
D'happy' and 'happiness' — -ness converts an adjective into a noun
'Runs' and 'ran' are both verbs meaning essentially the same thing — only the tense (grammatical information) differs. That is inflection: a change in form without a change in lexical category or core meaning. The other options all show derivation: adding -er or -ness changes the word's category (verb → noun, adjective → noun) or creates a new lexical entry with a distinct meaning.
Question 3 True / False
Languages like Mandarin, which have very little inflectional morphology, cannot express grammatical relationships like tense or number.
TTrue
FFalse
Answer: False
The absence of inflectional morphology does not mean the absence of grammatical expression. Mandarin conveys temporal information through adverbs (yesterday, tomorrow, already) and aspect markers; number through context or optional quantifiers. These languages are not simpler or less expressive — they use different strategies (word order, particles, context) to encode the same grammatical relationships that inflecting languages mark on word forms.
Question 4 True / False
Inflectional morphology changes the form of a word to express grammatical information without changing its lexical category or core meaning.
TTrue
FFalse
Answer: True
This is the defining property of inflection. 'Walk,' 'walks,' 'walked,' and 'walking' are all verbs meaning the same core action — they differ only in tense, agreement, and aspect (grammatical information). Compare this to derivation: 'walker' is a new word (a noun) with a new meaning. Inflection produces different forms of the same word; derivation produces different words.
Question 5 Short Answer
What is the key difference between inflection and derivation? Give an example of each using the same root word.
Think about your answer, then reveal below.
Model answer: Inflection produces different grammatical forms of the same word without changing its lexical category or core meaning (e.g., 'write' → 'writes,' 'wrote,' 'writing' — all still verbs meaning to write). Derivation creates a new word with a new meaning or different category (e.g., 'write' → 'writer' — a noun naming a person who writes).
The key test: after the morphological process, is the result still the same word (just in a different grammatical form), or is it a new word that could have its own dictionary entry? Inflected forms share a dictionary entry; derived words get their own. This is why dictionaries list 'write' without separately listing 'writes' or 'wrote,' but do list 'writer' as its own entry.
