difficult [hard] (to understand [solve])
出典:『Wiktionary』 (2013/05/21 16:31 UTC 版)
From difficulty, from Middle English difficultee, from Old French difficulté, from Latin difficultas, from difficul, older form of difficilis (“hard to do, difficult”), from dis- + facilis (“easy”); see difficile.
- Hard, not easy, requiring much effort.
- 2008, Daniel Goleman, Destructive Emotions: A Scientific Dialogue with the Dalai Lama (ISBN 0307483762), page 199:
- (often of a person, または a horse, etc) Hard to manage, uncooperative, troublesome.
Difficult implies that considerable mental effort or physical skill is required, or that obstacles are to be overcome which call for sagacity and skill in the doer; as, a difficult task. Thus, "hard" is not always synonymous with difficult: Other examples include a difficult operation in surgery and a difficult passage by an author (that is, a passage which is hard to understand).
