How Do You Spell ARDANESTHESIA, ARDANAESTHESIA?
Pronunciation: [ˌɑːde͡ɪnsθˈiːzi͡ə] (IPA) 
The correct spelling of the word is "anaesthesia" or "anesthesia" (US spelling). It's derived from the Greek word "anaisthēsis" which means "loss of sensation". The initial "a" in the word is pronounced as [ə], the "n" is pronounced as [n], the "ae" or "e" is pronounced as [iː], and the "s" is pronounced as [s]. Additionally, the "t" in "anaesthesia" is silent. Therefore, "ardanesthesia" or "ardanaesthesia" are not valid spellings of the word.
