'apotheosise' originates from Ancient Greek, specifically the word 'apothéōsis' (from 'apó' + 'theós'), where 'apó' meant 'away/from' and 'theós' meant 'god'. The verb form was formed in English with the suffix '-ize'/'-ise'.

'apothéōsis' (Greek) passed into Late Latin and then into English as 'apotheosis'; the verb 'apotheosize'/'apotheosise' was later created in English by adding the productive verb-forming suffix '-ize'/'-ise' to the noun.

Initially, the noun 'apotheosis' meant 'the act of making a god' or 'elevation to divine status'; over time the verb form came to mean 'to exalt or glorify (someone or something)' in both literal and figurative senses.
