Indefatigable describes a person or effort that persists tirelessly, refusing to yield to exhaustion or discouragement even under extreme pressure.
Quick Answer
Indefatigable is the ultimate descriptor for someone with an inexhaustible spirit. It refers to a state of being incapable of being fatigued, especially when pursuing a specific goal or duty.
Part of Speech: Adjective Pronunciation: IN-dih-FAT-ih-guh-bul (/ˌɪndɪˈfætɪɡəbəl/) Meaning: Persisting tirelessly; never showing signs of weariness or giving up.
The Spirit of Persistence
While words like energetic or hard-working describe a high level of activity, indefatigable describes a structural inability to quit. It is less about the speed of the work and more about the infinite nature of the fuel source.
An indefatigable person does not just work long hours; they operate as if the concept of tiredness is fundamentally alien to them. It is a word reserved for the marathon runners of life—human rights campaigners, obsessively driven inventors, or the grandmother who never seems to sit down until the entire family is fed and the dishes are polished.
The word often appears in historical accounts of leaders who managed to sustain momentum when their peers collapsed. According to biographers at the Churchill Project, Winston Churchill was frequently described as having an indefatigable temperament, often dictating memos late into the night while his staff struggled to keep their eyes open.
