idea (plural ideas or (philosophy, rare) ideæ)

1. (philosophy) An abstract archetype of a given thing, compared to which real-life examples are seen as imperfect approximations; pure essence, as opposed to actual examples. [from 14th c.]
   • 2013 October 19, “Trouble at the lab”, in The Economist, volume 409, number 8858:

     The idea that the same experiments always get the same results, no matter who performs them, is one of the cornerstones of science’s claim to objective truth. If a systematic campaign of replication does not lead to the same results, then either the original research is flawed (as the replicators claim) or the replications are (as many of the original researchers on priming contend). Either way, something is awry.

2. (obsolete) The conception of someone or something as representing a perfect example; an ideal. [16th–19th c.]
3. (obsolete) The form or shape of something; a quintessential aspect or characteristic. [16th–18th c.]
   • 1603, Michel de Montaigne, chapter 6, in John Florio, transl., The Essayes […], book II, London: […] Val[entine] Simmes for Edward Blount […], →OCLC:

     The remembrance whereof (which yet I beare deepely imprinted in my minde) representing me her visage and Idea so lively and so naturally, doth in some sort reconcile me unto her.

4. An image of an object that is formed in the mind or recalled by the memory. [from 16th c.]

   The mere idea of you is enough to excite me.

5. More generally, any result of mental activity; a thought, a notion; a way of thinking. [from 17th c.]
   • 1897 December (indicated as 1898), Winston Churchill, chapter III, in The Celebrity: An Episode, New York, N.Y.: The Macmillan Company; London: Macmillan & Co., Ltd., →OCLC:

     Now all this was very fine, but not at all in keeping with the Celebrity's character as I had come to conceive it. The idea that adulation ever cloyed on him was ludicrous in itself. In fact I thought the whole story fishy, and came very near to saying so.

   • 1952, Alfred Whitney Griswold, (Please provide the book title or journal name):

     Ideas won't go to jail.

6. A conception in the mind of something to be done; a plan for doing something, an intention. [from 17th c.]

   I have an idea of how we might escape.

7. A purposeful aim or goal; intent

   Yeah, that's the idea.

   • 1913, Joseph C[rosby] Lincoln, chapter III, in Mr. Pratt’s Patients, New York, N.Y., London: D[aniel] Appleton and Company, →OCLC:

     My hopes wa'n't disappointed. I never saw clams thicker than they was along them inshore flats. I filled my dreener in no time, and then it come to me that 'twouldn't be a bad idee to get a lot more, take 'em with me to Wellmouth, and peddle 'em out. Clams was fairly scarce over that side of the bay and ought to fetch a fair price.

   • 2013 June 1, “End of the peer show”, in The Economist, volume 407, number 8838, page 71:

     Finance is seldom romantic. But the idea of peer-to-peer lending comes close. This is an industry that brings together individual savers and lenders on online platforms. Those that want to borrow are matched with those that want to lend.

8. A vague or fanciful notion; a feeling or hunch; an impression. [from 17th c.]

   He had the wild idea that if he leant forward a little, he might be able to touch the mountain-top.

9. (music) A musical theme or melodic subject. [from 18th c.]
