What does molding mean?
Molding has two closely related uses. As a noun, it can mean a material that has been shaped in a mold, or a decorative strip fitted around the edges of a wall, ceiling, door, or window. Architectural molding is often made from wood, plaster, or polymer and serves both practical and ornamental purposes, concealing joints while adding visual detail. As a verb, molding means to shape material with a mold, as in the manufacture of buttons or plastic components. It can also be used figuratively when describing the formation of a person's character, habits, or behavior. The spelling molding is standard in American English, while British English normally uses moulding. The word is especially common in woodworking, construction, manufacturing, and interior design, where it refers both to the shaping process and to the finished decorative or structural form.
A material or object formed in a particular shape, especially by means of a mold; also, a decorative strip used to finish a surface or architectural joint.

The architectural sense is especially common in woodworking, interior design, and construction.
To shape material with a mold, or figuratively to form or influence someone's character or conduct.

Where does molding come from?
The word was formed in English by adding the suffix -ing to mold or mould. The earlier word came through Old French from Latin modulus, a diminutive of modius meaning a small measure. The same Latin root also produced English words such as module, modulus, modular, and modulate. The North American spelling molding and the British spelling moulding developed as parallel forms of the same word.
