jovian

the word jovian originates from the latin name for the supreme roman deity, iuppiter, whose alternative poetic name was iovis (jove). the genitive form 'iovis' gave rise to the combining form 'jov-', which was incorporated into english via latin. the suffix '-ian', derived from latin '-ianus', denotes connection or relation. thus, the literal construction 'of or pertaining to jove' was first used to describe things related to the mythological god. this meaning was later extended in the 17th century to the field of astronomy, as the largest planet in our solar system was named after this deity, leading to the modern sense of 'relating to the planet jupiter'.

Structure: jov (jupiter/jove) + ian (adjective suffix) jov (from latin 'iovis', the genitive form of 'iuppiter' or 'iovis', the name of the roman god jupiter, also called jove) + ian (a suffix of latin origin via french, used to form adjectives meaning 'belonging to' or 'relating to')
