bushed

This term is primarily used in informal, spoken English to describe a state of total physical or mental depletion. It carries a stronger connotation of exhaustion than "tired," suggesting that the person has reached their absolute limit and can no longer function effectively.

While it is common in North American and Australian English, it is rarely used in formal writing or professional reports. In those contexts, "exhausted" or "fatigued" are the appropriate substitutes. Because it is a participial adjective, it is typically used as a subject complement following a linking verb.
