To "immerse" means to fully engage or involve oneself in a particular activity or environment. This can refer to being surrounded by something, such as water, or deeply participating in an experience, like learning a new language or culture. When someone immerses themselves in a task, they focus entirely on it, often leading to a deeper understanding or appreciation. In education, immersion programs are designed to help students learn a language by surrounding them with it in everyday situations. For example, a Spanish immersion program might involve students speaking only Spanish during class and engaging with Spanish media, enhancing their language skills through constant exposure.
