How do you pronounce the name of Elon Musk and Grimes' baby 'X Æ A-12'?

Space X CEO Elon Musk and musician Grimes have announced the birth of their first child, a baby boy they've given a rather unusual name. 

Musk said told eager Twitter fans "mom and baby all good", later revealing the newborn was had been given the name "X Æ A-12 Musk". 

Whether or not Musk was in any way joking remains to be seen, but for now, the most hotly debated topic is exactly how that wacky name is pronounced. 

The front runner thus far appears to be a guess from Twitter user @flcnhvy, whose interpretation of the name as 'X Ash Archangel' was liked by Musk, leading fans to believe she might be onto something. 

The reasoning put forth stated that Æ - a letter of the Danish, Icelandic and Norwegian alphabets - was named 'ash' and that A-12 represented a CIA aircraft nicknamed 'Archangel'. 

Another fan suggested a biblical connection, wondering if the 'X' stood for Genesis, which happens to also be the title of a song by Grimes. 

"X = 10 in Roman numerals, 10 is an angel number representing God and his government on the earth, 'God said' appears 10 times in Genesis I. Grimes has a song titled 'Genesis'. Maybe X means Genesis," @tierney_mannion wrote. 

A third, equally complicated theory concluded the name was pronounced 'Jão'.

"X = 10 = J, Æ = ã, A - 12 (count backwards) = O," @langejanne tweeted. 

Some fans suggested Musk and Grimes had already made dedications to their baby through their respective projects. Musk purchased the domain name in 2017, and Grimes has a track entitled '4ÆM' on her new album.
