The British spelling of the present participle form of apotheosise, meaning to raise someone or something to the status of a god or treat them as divine.
From apotheosise (British variant of apothesize), which comes from Late Latin apotheosis, from Greek apotheoun 'to make a god,' composed of apo- 'away' and theos 'god.' The suffix -ising is the British spelling convention for verbs.
The British and American spellings of this word (apotheosising vs apotheosizing) reflect the Great Vowel Shift and later divergence of English spelling conventions—Britain kept closer to Greek roots while America simplified endings, creating this persistent 's' vs 'z' divide that confuses even native speakers!
