pronunciation of the words that make up an acronym have nothing to do with how you pronounce an acronym. see: atm is ay tee emm not aw tel mah nor is it atom. it’s just however it would make sense as a standalone word. some make a single sound and some require letter by letter and some combine.

soft ‘g’ jif makes perfect sense and is what the creator said is the the way it’s pronounced. hard ‘g’ gif sounds like someone saying ‘gift’ got candlejacked, thank you for coming to my ted tal
