It’s an acronym standing for graphic interchange format.
That doesn’t affect how it’s pronounced.
LASER stands for Light Amplification by Stimulated Emission of Radiation. If you were going to pronounce it based on how those words are pronounced it would be “Lahseer”.
The best reason to pronounce “gif” with a hard g is that the closest word we have is “gift” and that uses a hard g.
Just wanna say I didn’t downvote you.
I get your argument, maybe we SHOULD pronounce it lahseer, sounds cool.
Lahseer does sound cool, but I’m in favor of words being spelled as fonetikuhly as possible in English.
In order to do that, we have to clean up what each letter does first. The whole reason the gif fight started is because G and J overlap in sound values a lot. And don’t get me started on S, C, K, & Q.
