反義詞

Almost always modifies verbs that describe sustained, demanding work over weeks or years (campaigned, worked, fought, studied, searched). Rarely modifies short or one-off actions — saying someone 'jumped indefatigably' sounds odd because the activity is too brief.

常見錯誤

❌She answered the question indefatigably.
✅She campaigned indefatigably for years.
💡the adverb needs an activity that lasts long enough to show tireless effort.
❌He ran indefatigably for ten minutes.
✅He trained indefatigably for the marathon.
💡the duration is too short for 'indefatigably' to fit naturally.
