'commerciality' originates from English formation using the adjective 'commercial' plus the noun-forming suffix '-ity'; 'commercial' ultimately comes from Late Latin 'commercialis' and Latin 'commercium', where 'com-' meant 'together' and 'merx' meant 'goods'.

'commerciality' was formed in English by adding the suffix '-ity' to 'commercial' (from French/Latin roots). 'Commercial' came into English via Middle French and Late Latin (from 'commercium'), and the modern noun 'commerciality' developed from that adjective in later English usage.

Initially, roots related to trade and 'goods together' (commercium) referred simply to commerce; over time English developed 'commercial' to mean 'related to trade or profit', and then 'commerciality' to denote the quality or degree of being commercial (including modern senses like marketability).
