Which area of language will be the most affected by the age of onset for second language learning?

The area of language most affected by the age of onset for second language learning is typically the phonological aspect. Research has shown that individuals who begin learning a second language at an earlier age tend to achieve higher levels of native-like pronunciation and are better at distinguishing between phonetic sounds that are not present in their first language.

Younger learners tend to be more receptive to the subtleties of sounds and can more easily adapt their speech mechanisms to imitate the phonetics of a new language. In contrast, those who start learning a second language later often struggle with achieving similar pronunciation and may retain an accent from their first language.

Additionally, the cognitive development stage of younger learners allows them to acquire grammar and vocabulary more intuitively, making it easier for them to achieve fluency. Overall, while multiple areas of language acquisition are influenced by the age of onset, phonology stands out as a key area impacted significantly.
