From 中期英語 difficult (ca. 1400), a back-formation from difficulte (whence modern difficulty), from Old French difficulté, from Latin difficultas, from difficul, older form of difficilis (“hard to do, difficult”), from dis- + facilis (“easy”); see difficile. Replaced native 中期英語 earveþ (“difficult, hard”), from 古期英語 earfoþe (“difficult, laborious, full of hardship”), cognate to German Arbeit (“work”).
The verb is from the adjective, partly after Middle French difficulter and its etymon Latin difficultō. Compare difficilitate, difficultate, and Italian difficoltare.
difficult (comparative more difficult, superlative most difficult)
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. Examples include a difficult operation in surgery and a difficult passage by an author (that is, a passage which is hard to understand).
difficult (third-person singular simple present difficults, present participle difficulting, simple past and past participle difficulted)
Back-formation from difficulte (“difficulty”).
