   • 1801, Robert Southey, Thalaba the Destroyer:

     Ye wake no more to anguish;? ye have borne
     The Chosen, the Destroyer!? soon his hand
     Shall strike the efficient blow;
     Soon shaking off your penal forms, shall ye,
     With songs of joy, amid the Eden groves,
     Hymn the Deliverer’s praise!

   • 1856, William Dexter Wilson, An Elementary Treatise on Logic

     The Efficient Cause is that from which emanates the force that produces the Effect

Usage notes

Webster's Revised Unabridged Dictionary from 1913 still lists efficient and effective as synonyms, but all major dictionaries now show that these words now only have different meanings in careful use. Use of both for the other meaning is however widespread enough that Longman's Exam Dictionary, for example, finds it necessary to proscribe the use of one for the other with several examples at each entry and provides the following summary:

• efficient (“working quickly and without waste”)
• effective (“having the desired effect”)

Antonyms

• inefficient
