IPA: //ʌnˈwɪərɪd//
KK: /ʌnˈwɪrɪd/
Not feeling tired; having a lot of energy and enthusiasm without becoming weary.
She remained unwearied in her efforts to help others, even after a long day.
Unwearied → It is formed from "un-" (meaning not) and "wearied" (from Old English "werian", meaning to tire or exhaust). The word "unwearied" means not tired or exhausted, indicating a state of continuous energy or effort.
Think of 'not' ('un-') being added to 'tired' — that's why unwearied means someone who is not tired.
