IPA: /ˈmɔːrtərləs/
KK: /ˈmɔrtərləs/
Describing a structure or construction that does not use mortar to hold the materials together.
The ancient wall was built in a mortarless style, relying on precise stone placement.
Mortarless → It is formed from "mortar" (from Old French *mortier*, meaning a mixture used in construction) and "-less" (meaning without). The word "mortarless" means without mortar, referring to a construction style that does not use this binding material.
Think of a building that is 'without' ('-less') the 'mixture used in construction' ('mortar'). This helps you remember that 'mortarless' describes a structure that does not use mortar.
