Synonym discussion

Sense: adverb/1

Untiringly and its most common near-synonym tirelessly both describe action that continues without the person showing fatigue. Untiringly emphasises an enduring inner energy — the person simply does not become weary — while tirelessly often stresses the volume or duration of physical effort. Indefatigably is more formal and literary, reserved for praise of almost superhuman stamina. Relentlessly carries a stronger, sometimes negative tone of never stopping regardless of consequences, whereas persistently focuses on continuation despite obstacles or resistance. For example: 'She campaigned untiringly for better housing' suggests steady, admirable dedication; 'She campaigned relentlessly for better housing' suggests an aggressive, unstoppable push that may have upset opponents.

Etymology

Old EnglishEnglish

Untiringly is built from three English elements: the prefix un- meaning 'not', the adjective tiring meaning 'causing fatigue', and the adverb suffix -ly. The adjective untiring first appeared in the 17th century. The root tire comes from Old English teorian ('to become exhausted, fail, cease').
