The spelling of the word 'GRAE' may seem unusual, but it can be explained through phonetics. The initial 'G' is pronounced as a voiced velar stop [ɡ], followed by the long vowel sound 'ae' which is pronounced as [eɪ]. Therefore, the phonetic transcription for 'GRAE' is /ɡreɪ/. While this spelling may not be common in everyday language, it could be used in creative contexts to add an unusual or avant-garde touch to written works.
