Lexicon of words used in descriptions
For instance, the description 'an unlocked door' is made up from the adjective 'unlocked' and the noun 'door', both of which can be found below. Property adjectives, like 'open', can be used when creating things - 'In the Ballroom is an open container' is allowed because 'open' is a property - but those with complicated definitions, like 'empty', can only be tested during play, e.g. with rules like 'Instead of taking an empty container, ...'.
