Several kinds of messages can be set on 'things', objects that have $thing as an ancestor (see "help messages" for instructions on doing so). They are printed to various audiences under various circumstances when an attempt is made to 'take' or 'drop' a thing. The ones whose names begin with 'o' are always shown prefixed with the name of the player making the attempt and a single space character. The standard pronoun substitutions (with respect to the player) are made on each message before it is printed; see 'help pronouns' for details.
The default message is given in brackets after each name below:
@take_failed [Verb not found]
