amorous

The word 'amorous' has a direct lineage from Latin. Its core, 'amor', is the Latin noun for "love", itself derived from the verb 'amare', meaning "to love". The suffix '-ous', entering English via Old French from the Latin '-osus', imparts the meaning "full of" or "characterized by". Thus, the literal construction "full of love" elegantly captures the modern sense of being inclined to or expressive of romantic or sexual love. This clear semantic path from the concrete Latin root to the abstract English adjective makes its meaning intuitively logical.
