How do you evaluate evidence of language change in a given text?

• A. Rely on a single, dramatic instance as proof.
• B. Look for systematic, repeatable patterns across multiple texts and consider historical context and data reliability.
• C. Focus only on spelling differences.
• D. Dismiss data from earlier periods as unreliable.

Answer: (B)

The main idea is that evidence of language change should be evaluated by looking for systematic, repeatable patterns that appear across many texts, and by weighing the historical context and how reliable the data are. Change only becomes convincing when you can show the same feature recurring in different texts over time, not just in one dramatic example. You also need to place findings in their historical context—who produced the texts, when, and under what social or linguistic pressures—as well as assess the quality of the data, such as representativeness of the sample and accuracy of transcription.

Orthography alone can be misleading, since spelling can lag behind spoken language or reflect authorial convention rather than a genuine shift in usage. So, it helps to consider phonological, syntactic, or semantic changes where possible, and to triangulate evidence across multiple sources. This approach makes it possible to determine whether a change is real and widespread rather than incidental to a single text or writer.

So the best approach is to look for consistent patterns across multiple texts, while accounting for historical context and data reliability. A single dramatic instance, focusing only on spelling, or dismissing earlier material, would not provide a robust picture of language change.
