What term refers to features that can be learned at any time in the learner's development, such as vocabulary?

• A. Variational features
• B. Affective features
• C. Core features
• D. Fixed features

Answer: (A)

The idea is about features of a learner that can grow and change at any point in development. Vocabulary is a perfect example because you can keep learning new words throughout life, no matter where you are in your learning journey. This flexibility—being able to expand with exposure and practice—defines variational features. In contrast, fixed features stay the same once established, core features describe essential elements that don’t simply appear or disappear with time, and affective features relate to emotions or motivation rather than the content you can learn at any moment. So, vocabulary exemplifies something that can be learned and expanded whenever you encounter more language, making it a variational feature.
