"Also asked: Is it LAY-a or LEE-a?" Hamill tweeted.
Of course, Hamill doesn't offer any hints to the correct pronunciation. But this Leia debate has proof on both sides.
In A New Hope, right before Leia's home planet of Alderaan is destroyed, Tarkin pronounces her name name LEE-uh.
Senator Dodonna also calls her LEE-uh during the Death Star attack briefing prior the assault on the Death Star.
So it seems people who are close to Leia pronounce her name as LAY-uh. But when people who barely know her say her name, they pronounce it as LEE-uh. But thanks to Hamill's tweet, the debate will rage on over social media.
"No I disliked in A New Hope when the General was giving You and Wedge your duty," user JenniLynnHamill tweeted. "And R2's unit was stripped for the info and he said Princess LEE-a I had a heart attack because I yelled at the screen and said it's LEIA ITS LEIA L-E-I-A. as I sighed hard SMH like woah."
"She's a general and a princess so I had better get it right," user @TheGrizzlegrog tweeted.
"I always liked it that some characters pronounced it differently. It made the world more relatable," user @m0th3rst4r tweeted.
Disney and Lucasfilm didn't immediately respond to a request for comment.
