The phrase "Paps of Jura" refers to a range of three distinctive peaks located on the Isle of Jura in Scotland.
The word "pap" comes from the Old French word "pap," meaning "breast" or "nipple," which is likely due to the rounded shape of the peaks.
So, "Paps of Jura" literally translates to "Breast hills of Jura" or "Nipple hills of Jura."
