The spelling of the two-letter word "a z" can be peculiar and confusing. It is generally pronounced as "uh z" with the initial sound of the letter 'a' being a schwa sound, represented in IPA as /ə/. The second letter 'z' is pronounced as /z/. In some cases, 'a z' may also be pronounced as "ay zee" with the 'a' sound as in 'hay', IPA /eɪ/, and 'z' pronounced as /zi/. Despite its brevity, "a z" can cause hesitation even in experienced spellers.
