untired

Untired means not tired, exhausted, or worn out. It describes a person, animal, or body that still has energy and can continue an activity without needing rest. The word can also carry a more literary and positive suggestion of freshness, resilience, and unusual endurance, as in a reference to an “untired” or tireless traveler. In ordinary modern speech, people are more likely to say “not tired,” “rested,” “full of energy,” or “tireless,” depending on the intended nuance. Untired is therefore especially useful in literary, formal, or reflective contexts, where its old-fashioned character gives the description a vivid and elevated tone. It is less common as a plain factual description than its shorter contemporary alternatives, but it can express the combination of physical alertness and sustained vitality more distinctly.

Not tired; free from weariness or fatigue. In literary use, it can also suggest enduring energy, freshness, or an absence of exhaustion.
