Wikipedia:Concept cloud

A concept cloud is a brainstormed list of concepts that editors discuss as relevant to a topic, which are sorted in accord with their relevance, importance, and conceptualization &mdash;i.e. higher-order concepts take precedence. An outline, for example, is a kind of concept cloud, albeit with sequence and order of precedence in mind. Concept clouds instead are like outlines for a particular section (particularly the lead section), such that the entire body of concepts is arranged in a way removed from the usage of particular statements or expressions.

The concept cloud can help editors to overcome editorial struggles, and conceptualize, in a material way, the way an article is formed. From this mode of explicit and discrete concept listing, the various particular elements can be scrutinized and moved around intelligently without singling out the editing or writing skills of particular editors.

Form
A typical cloud is both a proactive object and a reverse-constructed form of an existing statement (reverse cloud). For example, the lead paragraph of the mathematics article currently states:

The reverse cloud is simply a disassembly of the above:

This reverse cloud can then be shown as an ordered list, with either room for comments (*), or a means to indicate particular terms (A 1, etc.):
