When one is discussing a concept, having a label to use to refer to it facilitates discourse, and identifies it as a specific idea, making the concept more mnemonic and usable, via chunking. See especially use of the term "thought experiment" on the value of naming a concept.
Naming concepts is useful both for technical jargon (within a specific work or field), or in common speech.
== Successful examples ==
Examples of names for concepts that have caught on:
Paradigm ShiftThese were both central ideas of a book.
Black SwanThese latter were the titles of books that focused on the concepts.
These are all two-word noun phrases; in some cases they use a more or less unusual word ("conspicuous", and "paradigm"), in other cases common words.
In all cases, there is a clear idea underlying them: the issue is simply to label it in a memorable and evocative way.
== Unsuccessful examples ==
Noosphere / Ideosphere / InfosphereThe "world of ideas & information" is a commonly understood concept that does not have a commonly accepted term, despite the above efforts. "Noosphere" is rather alien-sounding, while "infosphere" is too casual-sounding.
== High jargon fields ==
Technical fields tend to be higher in jargon, as one uses existing concepts to build higher concepts, hence one needs a way to refer concisely to these concepts.
== General principles ==
=== Avoid generic terms ===
For instance, in mathematics, "normal" means a bewildering array of distinct concepts.
=== Foreign terms ===
Loaned foreign terms can be memorable for their very foreignness: in physics, Gedankenexperiment is frequently used for thought experiment. One can also calque a phrase (translate it word-for-word).
