Origin and usage
The noun anosmia is formed from the prefix ‘an-‘ meaning ‘without’ or ‘not’, and the Greek ‘osme’ meaning ‘smell’. It was first used in the early 19th century.
The loss of a sense of smell or anosmia has been identified as one of the symptoms of COVID-19, experienced by some otherwise asymptomatic patients. The prefix a-, which changes to ‘an-‘ when it precedes a vowel, is used to indicate a lack or absence, as in ‘asymptomatic’. Other words with the ‘an-‘ prefix are anaerobic, meaning without oxygen; anaemic, without blood; and anorexic, which literally means without appetite. Anosmia is an entry in our crowdsourced Open Dictionary, submitted last year along with the related adjective anosmic. You can submit entries here.
