What does tired mean?
Tired describes a condition in which a person or thing needs rest, often because of physical exertion, illness, stress, or insufficient sleep. In this sense, it is a broad everyday adjective covering degrees of fatigue from mild sleepiness to complete exhaustion, although more specific words such as weary, exhausted, and fatigued may sound more formal or emphasize different aspects of the condition. Tired can also describe a loss of interest: when someone says they are 'tired of' a repeated activity, an argument, or a familiar routine, the word suggests boredom, impatience, or emotional weariness rather than physical fatigue. Common expressions include 'tired out,' 'visibly tired,' and 'tired from lack of sleep.' The adjective is widely used in both British and American English and can be paired with people, animals, and even machines or systems, as in 'the engine is tired.' Its flexibility makes it useful in everyday conversation, while its more literary relative 'weary' can add a formal or emotionally burdened tone.
adjectiveIn need of rest because of exertion, illness, or lack of sleep. By extension, feeling bored or no longer interested in something.
- Physically or mentally in need of rest.
- Bored, unimpressed, or no longer interested because of repetition or overexposure.
"After a long day of travel, she was too tired to cook and settled for a sandwich."
"The children were tired after playing outside all afternoon."
"I am tired of hearing the same excuse every time I ask."
Tired has a double life: it can describe a body running low on energy or a mind that has lost interest, allowing one everyday word to cover both physical fatigue and boredom.
