Etymology
the word 'copious' has a direct lineage from the latin adjective 'copiosus', which itself derives from the noun 'copia', signifying 'abundance, plenty, or resources' (from 'co-' [intensive] + 'ops' [wealth, power]). this etymological foundation directly informs the modern english meaning, as something described as copious is figuratively 'full of abundance'. the semantic journey is remarkably transparent, moving from the concrete notion of plentiful material supplies in latin to the more abstract application for anything existing in large quantity, including words or detail in speech and writing.
Analysis
copi originates from latin 'copia' meaning 'abundance, plenty, resources'. ous is an adjective-forming suffix from latin '-osus', meaning 'full of, characterized by'.
