What does vain mean?
Vain is an adjective with two related meanings. Applied to a person, it describes someone who is excessively proud of their appearance, abilities, or achievements, usually with the suggestion that they care too much about impressing others. This meaning often carries a dismissive or mocking tone. Applied to an attempt, hope, search, or effort, vain means that it is unlikely or unable to achieve a useful result; in this sense it is close to futile or hopeless. The phrase “in vain” means that an action was unsuccessful despite effort. Vain can therefore connect personal self-importance with the more general idea of emptiness or ineffectiveness. Its history reflects this range: the word developed from Latin vanus, meaning empty or without substance, and came to English through Old French. Today it is especially useful for distinguishing between merely unsuccessful efforts and efforts that were fundamentally bound to fail.
