Why is analyzing texts from different periods important for language change?

• A. It reveals how forms emerge, spread, or disappear across time and context.
• B. It helps build a definitive dictionary of a language.
• C. It proves language never changes.
• D. It focuses mainly on spelling conventions.

Answer: (A)

Studying texts from different periods lets us see how linguistic forms come into being, spread through communities, or fade away over time and in different contexts. This diachronic view shows why changes happen—social contact, literacy, technology, and cultural shifts influence which forms endure and which drop out. For example, tracking pronoun use or spelling over centuries reveals how societies move toward standardization and simplification, and how new words and meanings enter the language. The other options miss the broader purpose: building a single dictionary is a byproduct of documenting language, not the main aim of analyzing change; the idea that language never changes is directly contradicted by this approach; and focusing only on spelling conventions ignores the wider shifts in grammar, pronunciation, and vocabulary that such analysis exposes.
