Question

Quizplus · Accepted Answer

Age of acquisition is the best predictor of second language fluency. Studies have shown that younger learners have a greater capacity for acquiring native-like pronunciation, grammar, and vocabulary use. Generally, it is more difficult to attain full fluency in a second language if the acquisition starts after childhood. Motivation is also an important factor, but it is not as reliable a predictor as age of acquisition. IQ and the simplicity of the language structure do not have significant correlations to second language fluency.
