- n. Physical power of endurance; toughness.
- n. Synonyms Courage, resolution, pluck, stoutness, fortitude; audacity, effrontery, assurance, impudence. The unfavorable meanings of hardihood seem to be prevailing over the good ones, so that there is a tendency to look to other words for the expression of courage and endurance. The issue of this tendency is not yet decided; it is less marked in the case of hardy.
