Synonyms: tire1, weary, fatigue, exhaust
These verbs mean to cause or undergo depletion of energy, strength, or interest. Tire often suggests a state resulting from exertion, excess, dullness, or ennui: "When a man is tired of London, he is tired of life" (Samuel Johnson).
Weary often implies dissatisfaction, as that resulting from what is irksome or boring: found the long journey wearying; soon wearied of their constant bickering. Fatigue implies great weariness, as that caused by stress or overwork: "fatigued by an endless rotation of thought and wild alarms" (Mary Wollstonecraft).
To exhaust means to wear out completely, and it connotes total draining of physical or emotional strength: "Like all people who try to exhaust a subject, he exhausted his listeners" (Oscar Wilde). "Following a similar 'tempest' he had ... actually apologized to me for his misbehavior ... Scenes such as I had just been a participant in fractured my spirit, exhausted me" (William Styron).
