the word 'ubiquitous' is a modern english formation, coined in the 19th century directly from the latin adverb 'ubique', meaning 'everywhere'. the latin term itself is a compound of 'ubi' ('where') and the suffix '-que' (a generalizing particle meaning 'any'). the suffix '-ous' was appended, following the pattern of other english adjectives derived from latin, to create a term meaning 'characterized by being everywhere'. the logic of the word's construction is transparent: it literally means 'full of everywhere-ness', which perfectly captures its modern sense of something being omnipresent or found in all places.

Structure: ubique (everywhere) + ous (adjective suffix) ubique (from latin 'ubique', meaning 'everywhere'); ous (from latin '-osus', an adjective-forming suffix meaning 'full of' or 'characterized by')
