Note: ☞ The present tense, I dare, is really an old past tense, so that the third person is he dare, but the form he dares is now often used, and will probably displace the obsolescent he dare, through grammatically as incorrect as he shalls or he cans.
Note: ☞ Formerly durst was also used as the present. Sometimes the old form dare is found for durst or dared.
