Example Citation:
"[Older women] are celebrating their accumulated years and grey hairs. To mark the rite of passage, they have appropriated the old English word 'crone' and reinvested it with a more positive meaning. Cronehood is the third stage of womanhood, after youth and motherhood, explained Betty Nickerson, an author and founder of Amazing Greys, an annual retreat in British Columbia for crones and crones in training."
