libidinous

the word 'libidinous' is built directly upon the latin noun 'libido', which signifies strong desire, particularly of a sexual nature. this latin root itself is derived from the verb 'libet' or 'lubet', meaning 'it pleases' or 'it is desirable', tracing further back to the proto-indo-european root leubh-, expressing love, care, or desire. the suffix '-ous', borrowed from latin via french, attaches to nouns to form adjectives meaning 'full of' or 'having the qualities of'. therefore, the literal construction 'full of libido' evolved seamlessly into the modern abstract meaning of being characterized by or driven by lustful desires.

Structure: libidin (desire, lust) + ous (adjective suffix) libidin (from latin 'libidin-', stem of 'libido', meaning desire, lust, pleasure); ous (english adjective-forming suffix, from latin '-osus', meaning full of, characterized by).
