The duty of grammarian is a Club Meeting Role. The grammarian keeps track of good and bad grammatical usage, records use of the Word of the Day and reports when called upon.
The role is simetimes combined with that of Ah Counter.
Clubs differ in their handling of the Word of the Day. Some clubs require that it be used in a Table Topics response. Some don't require its usage but recognize the members who used it during the meeting. Yet other clubs have a theme for each meeting, and the Word of the Day usually fits in with the theme.
