Steve Kaufman's method for learning languages is based on comprehensible input, which means learning a language by listening and reading messages that are understandable to the learner. This method is supported by famous linguists such as Stephen Krashen, who argues that language acquisition occurs through comprehensible input rather than through explicit grammar instruction or memorization of vocabulary lists. Kaufman emphasizes the importance of enjoying the language learning process and trusting the brain's ability to gradually form patterns and produce the language. He also recommends meandering interleaving, which involves learning a bit of this and a bit of that, rather than trying to block learn anything.
