Language both influences and is influenced by thought and reality. While language allows us to express concepts about the world, it is mediated by cognition and context. Different languages categorize concepts differently due to the experiences and needs of their speakers. For example, Inuit languages have over 50 words for snow due to their reliance on distinguishing snow conditions. Language also uses deixis, or elements requiring context, to refer to reality, such as pronouns referring to people or places. Overall, language, thought, and reality have a complex and reciprocal relationship.
