The spelling of the word "FAXS" might seem unusual, but it is actually a plural form of "fax" pronounced as /fæks/. The IPA phonetic transcription for "fax" is /fæks/, which is a short vowel sound for "a" followed by a voiceless consonant "x". When "fax" is made plural, an "s" is added, resulting in "faxes" pronounced as /fæksəz/. However, for some inexplicable reasons, the spelling of the plural form has been modified to "faxs."
