GRAHCO serves the roles of Grammarian, Ah Counter and WordMaster. Ah Counter counts the number of times each person uses unnecessary filler words such as 'ah' and 'um' instead of a stately pause.
The Grammarian records grammatical errors. WordMaster presents the Word of the Day which is a new or little known word for us to learn and records the number of times each person uses it during the meeting. GRAHCO reports the result at the end of the meeting.
