Which hypothesis suggests that authentic language acquisition is necessary for effective language use?

The acquisition-learning hypothesis posits that there are two distinct processes involved in language development: acquisition and learning. According to this hypothesis, acquisition refers to the subconscious process of internalizing language through meaningful interaction and immersion in the target language, while learning is a more formal and conscious process of understanding grammatical rules.

The crux of this hypothesis is that authentic language acquisition, which occurs through genuine communication and meaningful context rather than through rote memorization or explicit instruction, is crucial for effective language use. This implies that for learners to truly use a language fluently and naturally, they must engage with it in contexts where they can acquire the language intuitively.

This approach emphasizes the importance of real-life language use, suggesting that the best way to become proficient in a language is through experiences that promote authentic interaction. This hypothesis aligns closely with communicative language teaching methods that prioritize language use in context over mere formal instruction.
