Basically, is there a word that relates "carpenter" to "carpentry" or "astronomer" to "astronomy"?

So if there is a subject that does some noun, is there a word or phrase for that relationship?


Sample sentence: "'activist' is a _________ of 'activism'." or "'architect' is a _________ of 'architecture'."

practitioner noun [ C ] formal UK /prækˈtɪʃ.ən.ər/ US /prækˈtɪʃ.ən.ɚ/

A proponent is 'one who does something'. Or it can be 'one who promotes something - propels it forward.

  • A carpenter is a proponent of carpentry

  • An architect is a proponent of architecture

  • An activist is a proponent of activism

From the Latin proponere 'to put forward' https://www.etymonline.com/word/proponent

The word is usually described in dictionaries as someone who 'puts forward an argument' but it means more than that - it can mean to 'push forward' an industry, activity, way of being, thought, or art form - which is often done through action, and activity, not merely by talking.

If you want to 'be a proponent of eco architecture' for example, you could simply be talking about it, but another way of being a proponent would be to actually build an eco village that people can visit.

  • Dickens - was a proponent of social reform (through his books)
  • Madonna - is a proponent of women's sexual freedom (through her mode of dress, behaviour and way of being etc)
  • Starbucks - is a proponent of great coffee
