The Spanish verb 'adornar' (to adorn) comes from the Latin word 'adornare', meaning 'to furnish' or 'to decorate'. The Latin 'adornare' itself was formed by combining two elements: the prefix 'ad-' meaning 'towards', and the verb 'ornare' meaning 'to equip' or 'to adorn'. This combination enhanced the basic meaning of 'ornare', emphasizing the act of adding decoration or embellishment to something.

Some related Spanish words include 'ornamento' (ornament), 'ornamental' (ornamental), and 'ornamentación' (ornamentation). These words share the same Latin root 'ornare' and maintain similar meanings related to decoration and embellishment.

English speakers might recognize the connection to words like 'adorn', 'ornament', 'ornate', and 'ornamental'. These English words come from the same Latin roots as the Spanish 'adornar'. The English 'adorn' is particularly close in both form and meaning to the Spanish 'adornar', making it easy to remember. Both languages preserved the original Latin meaning of decorating or embellishing something.
