I think this is originally a term used in biology or evolution theory. I heard it in a youtube video but I cannot find it now.

Edit: This word does not have negative connotations. For instance, an animal may develop a different way to use an organ intended for something else. Or you can use a big book as a door stop.

    Why not repurposing? – bib Jan 12 '14 at 21:23
  • I think repurposing works as well; in fact I was looking to repurpose exaptation to mean repurpose. – Zeynel Jan 12 '14 at 21:39
  • Your question is not clear. If I presumed I had clarity of the question, I would answer it with malapropism - but I will not since I have scant idea if that is what you would be looking for, since it has nothing to do with biological Evolution. – Blessed Geek Jan 13 '14 at 3:10
  • As a biologist, I'd be more inclined to refer to an original purpose rather than intended purpose - "intention" (and to a lesser extent, "purpose") sounds like intelligent design. – Andrew Grimm Apr 3 '15 at 5:55

Ok, I found the answer: exaptation.

    Your title is dubious . Exaptation is a change in function of a trait during evolution ,( the purpose of it changes but there is no mention of – Argot Jan 12 '14 at 20:17
  • Other use than intended purpose. – Argot Jan 12 '14 at 20:22

    Though I would like to know the answer of the title question and not the anticipated question. – Argot Jan 12 '14 at 20:24

    in a biological sense, i believe this is most certainly the correct word. for those looking for something WITH the negative connotations, "subvert" comes to mind – chrismarx Mar 18 '15 at 17:41

Using "improvise" and "improvisation" in a sentence to illustrate the meaning:

We lacked the purpose-built equipment to do the task, so we had to improvise, using only the tools available.

Our improvisation of using a garden hoe to mix the cement worked well.


@Argot -what's the answer to the title?

ad hoc
Latin, meaning: for this -Wiki

ad hoc can also mean makeshift solutions, shifting contexts to create new meanings, inadequate planning, or improvised events.

Palimpsest. A beautiful word and a magical thing. "Something such as a work of art that has many levels of meaning, types of style, etc. that build on each other," according to the Cambridge Dictionary.

  • The Shabaka Stone in the British Museum was once a monumental stela recording events 1000's of years ago but became a millstone for grinding grain and then a part of a wall. It carries all those complex histories in one simple stone 'wheel'. – Annie Smart Feb 16 '18 at 19:07

    Not my downvote, could be the voter needs to be convinced. Could you provide a definition from an online dictionary, or make a sentence with your suggestion? (I think you're on the right track btw) – Mari-Lou A Oct 8 '14 at 5:11
  • I agree with Mari-Lou A that this might well be the best verb suggestion. It's a shame that the user who put it forward never attempted to develop the suggestion into a complete answer, with (for example) a suitable definition of the suggested term and a brief explanation of how it meets the questioner's conditions. – Sven Yargs Aug 27 '15 at 5:23
