Which illustrates Lexical Semantics?

• A. The words big and large are synonyms
• B. The sentence 'She eats apples'
• C. The pronunciation difference between the p sounds in phone and pin
• D. The spelling of receive follows i before e after c

Answer: (A)

Lexical semantics focuses on word meanings and how words relate to each other in a vocabulary. The best illustration here is recognizing that big and large are synonyms, meaning they share similar meanings and can often be used interchangeably in the right contexts. This shows how words connect in the mental lexicon through meaning relationships. The other options point to different areas: a sentence example highlights how words combine in a structure (syntax/grammar), the p sound difference is about how sounds are produced (phonology), and the spelling rule about i before e after c concerns spelling conventions (orthography). So, the relationship of meaning between synonyms is the clearest demonstration of lexical semantics.
