What term refers to possible ideas about language rules that learners form and test through use, changing as new information is received?

• A. Hypotheses
• B. Theories
• C. Rules
• D. Assumptions

Answer: (A)

The main idea is that learners form provisional ideas about how language rules work and test them through actual use, updating them as new information comes in. These ideas are like educated guesses about what is possible or correct, and they’re meant to be tested and revised when learners encounter new examples, corrections, or outcomes in real communication. That’s why the term best fitting this process is hypotheses: it names ideas that are tentative, testable, and open to change based on evidence from language use.

Think of it as the learner’s working bets about language behavior. If a pattern of usage fits the evidence, the hypothesis gains support; if new input contradicts it, the learner revises or replaces it. Theories, in contrast, are broader, more established explanations built from many observations and not necessarily reshaped on the fly by a single learner’s experiences. Rules imply fixed, prescriptive norms, not flexible, testable conjectures. Assumptions are beliefs held without testing. Only hypotheses capture the idea of tentative, testable ideas that evolve with experience.
