The Spanish verb 'ornamentar' (to ornament or decorate) comes from the Latin roots 'ornare' (meaning 'to adorn or equip') combined with the instrumental suffix '-mentum'. These elements first formed the Latin word 'ornamentum' meaning 'ornament or equipment', which evolved into the Spanish noun 'ornamento'. The verb 'ornamentar' was then created by adding the Spanish verb-forming suffix '-ar' to 'ornamento'.

This etymology shows how Spanish created a verb meaning 'to decorate' by building upon the noun form, similar to how English can use 'ornament' as both a noun and a verb.

The Spanish noun 'ornamento' is a simpler and more common related word, meaning 'ornament' or 'decoration'. You might also encounter 'ornamental' as an adjective meaning 'decorative'. These words share the same Latin root 'ornare' and are part of the same word family focused on decoration and embellishment.

English speakers can easily connect 'ornamentar' to several familiar English words like 'ornament', 'ornamental', and 'ornamentation'. All these words come from the same Latin source 'ornare'. The connection is clear both in spelling and meaning - they all relate to decoration and embellishment. Even the English word 'adorn' is a distant cousin, coming from Latin 'adornare', which combines 'ad-' (to) with 'ornare'.
