Am I the only one around here who has read Regency novels?
Wherein it is pronounced with a long O not as in ton/weight. In said Regency novels "ton" is used in reference to the upper class in society - every young girl's ambition to be accepted by the "ton" and invited to all the right parties and perhaps find a husband. At best to fall in love with said man or at least like him but in any case to make "a good marriage."
Gawd but I have wasted some time in my days!
On the other hand they were enjoyable escapes for a few hours.
