resinous

the word 'resinous' is a direct derivative of the noun 'resin', which entered english from old french 'resine', tracing back to latin 'resina'. the latin term is believed to be borrowed from greek 'rhētinē', referring to the pitch of pine trees, a substance whose origins are likely pre-greek. the adjectival suffix '-ous', of latin origin, is productively attached to nouns to denote possession or character. thus, the literal construction 'full of resin' logically evolved into the modern descriptive meanings pertaining to the properties, content, or appearance of resin.

Structure: resin (substance) + ous (adjective suffix) resin (from latin 'resina', meaning a sticky substance from plants); ous (from latin '-osus', a suffix forming adjectives meaning 'full of' or 'having the qualities of')
