What is the main difference between a diachronic linguistic approach and a synchronic linguistic approach?

• A. Diachronic examines change over time; synchronic examines language at a single time.
• B. Diachronic focuses on written forms; synchronic focuses on spoken forms.
• C. Diachronic analyzes language across regions; synchronic analyzes historical development.
• D. Diachronic studies grammar rules only; synchronic studies vocabulary.

Answer: (A)

Time is the deciding factor. A diachronic approach follows how a language changes across periods, tracing shifts in sounds, vocabulary, and grammar from one historical stage to another. A synchronic approach looks at the language at a single moment, studying its structure and patterns as a complete system without considering how it got there.

So, the main difference is that diachronic examines change over time, while synchronic examines language at a single time. For example, diachronic work might map the Great Vowel Shift through English history, whereas synchronic work would analyze the grammar of Modern English as it functions now. The other descriptions mix up aspects like mode (written vs spoken), geography, or a focus on one linguistic domain, rather than capturing the essential time-related vs. snapshot distinction.
