The Origin of Moulding or Molding

The word “mould” comes from Old French “modle”, meaning a form or shape. In architecture, “moulding” referred to decorative trim as far back as the 15th century.

In American English, the spelling simplified to “molding” dropping the “u” thanks to Noah Webster’s spelling reforms.

Tip: For industrial contexts, remember injection moulding or molding refers to shaping materials like plastic, not decorative trim.
