Which is an example of Morphology?

• A. The word unhappiness is formed from the root word happy with the prefix un- and the suffix -ness
• B. The sentence 'The cat sat on the mat'
• C. The phrase 'Can you pass the salt?' is a polite request
• D. The spelling rule 'i before e except after c'

Answer: (A)

Morphology is the study of how words are built from smaller meaningful pieces called morphemes. This example shows that clearly: unhappiness comes from the root happy plus the prefix un- and the suffix -ness. The prefix adds negation, and the suffix changes the part of speech to a noun, illustrating how morphemes combine to form new words and meanings. The other options point to sentence structure (syntax), how we use language in social context (pragmatics), and spelling rules (orthography), not how new words are formed from morphemes. So this example best demonstrates morphology.
