the word 'strappy' is a modern english formation, directly built upon the noun 'strap'. the root 'strap' has a long lineage, tracing back to ancient greek strophos, meaning a twisted band or cord, which passed into latin as stroppus and into old english as stropp. the core concept of a narrow, flexible band has remained remarkably consistent. the adjectival suffix '-y', of germanic origin, is productively attached to nouns to indicate possession or abundance of that quality. therefore, 'strappy' literally means "having straps" or "characterized by straps," a straightforward descriptive term for footwear or garments where straps are a defining design element.
