This article explains how producing language helps learners notice gaps, test grammatical hypotheses, reflect on language forms, and develop greater fluency and accuracy in a second language.

The Input Hypothesis, developed by Stephen Krashen, argues that people acquire a language when they understand meaningful input that is slightly beyond their current level. This article explains the role of comprehensible input, the idea of “i+1,” the difference between acquisition and learning, and the lasting influence of the theory on language teaching and second language acquisition research.
