Etymology and History:

The English word "crust" originates from the Latin "crusta," meaning "rind" or "shell," evolving through Old French "croste" in the 14th century. It has been used in English since the Middle Ages, initially for food crusts, and later expanded to geological terms in the 19th century during scientific advancements. In Thai, "เปลือก" derives from ancient Sanskrit influences, reflecting historical trade and cultural exchanges.

A plague upon the tyrant that I serve! I'll bear him no more sticks, but follow thee, Thou wondrous man." Here, "crust" isn't directly used, but the theme of natural elements parallels geological crusts. Source: The Complete Works of William Shakespeare.
