The concept of the "affective filter" refers to a metaphorical barrier that can influence a learner's ability to acquire a new language, primarily due to emotional factors such as anxiety, self-esteem, and motivation. When learners are anxious or fearful, their affective filter is high, which can hinder the absorption of linguistic input because they may be less receptive to learning opportunities.

In this context, if a student feels uncomfortable or anxious in a language classroom, their affective filter raises, which can impede their ability to engage with the language effectively. Conversely, when students feel relaxed and motivated, their affective filter lowers, allowing them to interact more freely with the language and fostering better acquisition. This understanding emphasizes the importance of creating a supportive, low-anxiety learning environment for language learners, encouraging instructors to be attentive to their emotional and psychological needs during the learning process.
