unwearied
Still going strong
Unwearied means not tired or fatigued, maintaining energy and persistence despite prolonged effort.
The word typically describes sustained dedication rather than mere physical stamina: unwearied devotion to her students, an unwearied pursuit of justice.
It's literary and somewhat old-fashioned, more common in formal or elevated prose than everyday speech.
