Which terms have their own pages?
Terms that carry enough regulatory substance to earn one — the revenue measures (GGR, NGR, GGY), the compliance layer (KYC, AML, source of funds), the market-structure vocabulary (grey and black markets, point of consumption and supply, white labels, B2B/B2C) and the player-protection machinery. One-line entries stay on this page.
Why does so much of the vocabulary involve money?
Because regulation is implemented through money: the tax base defines the operator’s burden, the revenue measure defines the licence fee, and the deduction rules define who keeps what. Most regulatory arguments are, at bottom, arguments about which number applies.
Are these definitions jurisdiction-specific?
The concepts travel; the details do not. GGR means the same thing everywhere, but what may be deducted from it, which register a licensee must check, and when KYC must complete are all answers that change at every border — the country profiles carry the local specifics.
A term I expected is missing — why?
The lexicon grows with the atlas: terms are added when the country profiles, licence pages or tracker entries need them, so coverage follows the regulatory content rather than aiming at dictionary completeness. The methodology page describes how the site decides what earns a page.
