I think childhood is the best time to learn a foreign language. Kids are like sponges; they absorb everything around them, including languages. Their brains are wired to pick up new sounds and structures easily. Plus, when they learn a language early, they tend to have better pronunciation and fluency. It's also easier to make language learning a part of their daily routine, which helps them practice more.

Adolescence is a great time to learn a foreign language. Teenagers have developed cognitive skills that help them understand complex grammar. They can also relate language learning to their interests, like music or movies, making it more engaging. Schools often provide structured language programs, and teenagers can focus on exams and certifications. Plus, they have opportunities for language exchange programs and travel, which enhance their learning experience.

Adulthood can be a good time to learn a foreign language too. Adults often have specific motivations, like career advancement or travel, which drive them to learn. They have access to a wide range of resources, such as online courses and language apps. Their life experiences provide context for language learning, and they can practice in real-world situations. Adults also tend to have more patience and discipline, which helps them study consistently.
