The age of acquisition is the best predictor of whether someone will achieve fluency in a second language. Research suggests that language acquisition becomes more difficult after puberty, with those who begin learning a second language before age 7 having a significantly better chance of achieving native-like fluency. Motivation, IQ, and simplicity of language structure can all impact language learning, but they are not as significant as the age of acquisition.
