Why is it important to use multiple texts or corpora when studying language change?

• A. To avoid anomalies and to obtain a representative picture of widespread change.
• B. To focus on a single author’s voice.
• C. To memorize dates of changes.
• D. To ignore cross-text variation.

Answer: (A)

When you study language change, the aim is to see how language shifts across communities over time, not just in one instance. Different texts reflect different contexts—speakers, regions, ages, genres—and relying on a single text can make you miss how widespread a change is or, worse, misread a quirk of that author or genre as a general trend. Using multiple texts or corpora lets you sample broadly and quantify patterns, so you can tell whether a feature is common across many contexts or confined to a small group. It also helps you track how usage shifts over time and compare varieties, ensuring you identify genuine trends rather than anomalies. In short, broad data reduces the risk of overgeneralizing from an anomalous example and provides a representative picture of language change. Focusing on a single author or trying to memorize dates, or ignoring cross-text variation, would all miss the broader, population-level nature of linguistic change.
