• D. The persistence of language without change

Answer: (A)

Language change is the historical shift in a language’s features over time. It includes changes in sounds (pronunciation), grammar, vocabulary, and usage as communities interact, borrow from others, or adapt to new circumstances. Think about examples like the Great Vowel Shift, which altered English vowel sounds over centuries, or the move from using “thou” to “you” in everyday speech. New words enter a language and old ones fall out of use as technology, culture, and contact with other languages influence speakers. This topic is studied to understand how languages evolve across generations, which distinguishes it from looking at differences among speakers at one moment (variation), or from writing systems (orthography).
