'artiness' originates from English, specifically formed from the adjective 'arty' plus the suffix '-ness', where 'arty' is derived from 'art' meaning 'skill, craft' and '-ness' is a noun-forming suffix indicating a state or quality.

'art' came into English via Old French 'art' from Latin 'ars, artis'; the adjective 'arty' developed in English (informal use, later 19th century), and 'artiness' was formed from 'arty' + '-ness' to denote the quality or state.

Initially related to 'art' in the sense of skill or craft, the derived forms ('arty', 'artiness') have come to mean 'affectedly artistic' or 'pretentiously artistic' in modern usage.
