I want to know the answer to the following question:
What  is the origins of the term "old woman " ?
All the background I'm provided with is that "The word γραῖα graia "old woman" comes from the PIE root *ǵerh2-/*ǵreh2-, "to grow old" via Proto-Greek *gera-/grau-iu; the same root later gave γέρας geras (/keras/), "gift of honour" in Mycenean Greek.". Is that enough to answer the question?
Answer: yes
