The SRD gives us a helpful list of possible ranges for spells: Personal, Touch, Close, Medium, Long, Unlimited, and Range Expressed in Feet. However, this is clearly not a comprehensive list of all of the possible range categories in the game. For example, Persistent Spell's text claims that "Spells with a fixed or personal range can have their duration increased to 24 hours". This is despite, to my knowledge, "fixed range" not being a term that is defined in game or obviously understandable in plain English (e.g. this question shows one potential source of confusion).
This leads me to my question: What range categories does the game acknowledge, what are their definitions, and where are these definitions found or derived from?
