In a time when women were restricted by social etiquette norms, the fan was also used as a means of communication. A book published in 1797, Fanology or the Ladies Conversation Fan, gave a list of explicit instructions on how to use it to convey discreet messages. According to the book, the English alphabet was divided into five hand positions (with the letter J excluded):

? Hold the fan in left hand and touch your right arm = A–E

? Hold the fan in right hand and touch your left arm = F–K

? Place the fan against your heart = L–P

? Raise the fan to your mouth = Q–U

? Raise the fan to your forehead = V–Z
