The phrasal verb 'let down' is predominantly used in informal contexts, although it can appear in formal situations as well when the setting allows for a conversational tone. It generally means to disappoint someone by failing to meet their expectations or failing to fulfill a promise. Common usage contexts include personal relationships, where someone might feel let down by a friend's actions or commitments not being honored, or in professional settings where an employee might let down their manager by not completing a task. Additionally, 'let down' can be used in a literal sense to describe a physical lowering, such as letting down one's hair or a physical object being released or lowered. The phrasal verb can be both transitive and intransitive, depending on the context. Its informal usage ensures its presence primarily in spoken language, although it finds its way into written communication such as emails or informal reports, where direct language is preferred.
