Ancient words borrowed from along the Silk Road since Old Chinese include "pútáo" "grape", "shíliu"/"shíliú" "pomegranate" and / "shīzi" "lion". Some words were borrowed from Buddhist scriptures, including "Fó" "Buddha" and / "Púsà" "bodhisattva." Other words came from nomadic peoples to the north, such as "hútòng" "hutong". Words borrowed from the peoples along the Silk Road, such as "grape," generally have Persian etymologies. Buddhist terminology is generally derived from Sanskrit or Pāli, the liturgical languages of North India. Words borrowed from the nomadic tribes of the Gobi, Mongolian or northeast regions generally have Altaic etymologies, such as "pípá", the Chinese lute, or "lào"/"luò" "cheese" or "yogurt", but from exactly which source is not always clear.
