Whenever I am encountering an abstract concept internally, it does not appear as a clear visual representation but rather as its gestalt. Then there are two things happening. 1. most of these seem to bring their own set of keywords with them. 2. on the basis of these keywords I can further probe the concept using my internal monologue, like using a spotlight to get more details and pulling it out of the twilight of its gestalt. Step 2 is only necessary to explain the concept to others or put it in writing. All in all the transfer from gestalt concept to language sure leaves something behind but it also adds something that it could not have on its own.
