I’m not deeply familiar with WTW (I mainly use it just for generating ‘unguessable’ passwords ;)) but I understand that the dissimilarity between proximate 3-word locations is deliberate, to prevent or reduce the risk of a location transmitted over a bad connection from being misheard. If, for example, a rescue service hears a downed climber in the Andes calling for rescue at, say, ‘spirits.leaders.scrawls’ and mishears at as ‘spirits.leaders.crawls’ as soon as they enter it into the map they will know it is incorrect, and request clarification, precisely because it is nowhere near the Andes. (‘spirits.leaders.crawls’ is in Hawaii)
