美國當地時間5月5日凌晨，馬斯克迎來了與歌手女友格萊姆斯的第一個孩子，也是馬斯克的第六個孩子。
這個馬斯克最小的兒子被取名為XÆA-12 Musk。此前，格萊姆斯解釋過兒子名字的由來：其中X代表的是未知數，Æ，就是AI（愛或人工智能）的精靈語拼寫。
這次採訪中，馬斯克也講述了小兒子名字的來龍去脈。
馬斯克稱，這個名字大部分是女友想的，她在取名字方面很在行。在兒子的名字中，X的發音就像字母X一樣，Æ的發音像ash，A-12部分則是自己的主意。之所以會用到A-12，是因為這是史上最酷的飛機SR-71偵察機的前身。
Elon Musk and Grimes reveal how to pronounce baby's name -- but they disagree
Elon Musk and Grimes have garnered plenty of attention since announcing the name of their newborn baby, but now it seems they can't agree on how it should be pronounced.
Speculation over the name X Æ A-12 has been a major topic of conversation since the couple welcomed the baby boy into the world on Monday, with questions over what the characters mean.
●speculation 猜測；推測，推斷
Rumours that they are about to marry have been dismissed as pure speculation. 他們打算結婚的傳言已證實只不過是猜測。
Speculation about his future plans is rife. 對他未來的計劃猜測很多，眾說紛紜。
The Canadian musician -- real name Claire Elise Boucher -- previously explained that Æ is the Elven spelling of AI, which is shorthand for artificial intelligence.
"It's just X, like the letter X. Then A.I. Like how you said the letter A then I," wrote Grimes on Thursday in response to a query on Instagram.
However, Musk told podcast host Joe Rogan a different pronunciation of the name in a conversation released Thursday, even as he credited Grimes for coming up with the moniker.
●moniker 名字；綽號
"First of all, my partner is the one that, actually, mostly, came up with the name," the Tesla and SpaceX CEO said. "Yeah, she's great at names."
Rogan then asked how to say it, to which Musk responded: "I mean it's just X, the letter X. And then, the Æ is, like, pronounced 'Ash'... and then, A-12, A-12 is my contribution."
This is the couple's first child together. Musk has five other children -- twins Griffin and Xavier and triplets Damian, Saxon and Kai -- from a previous marriage, and Rogan asked how it felt to have another child now.
The parents don't seem to agree on how to pronounce their baby's unusual name.
"Actually I think it's better being older and having a kid," said Musk. "I appreciate it more. Babies are awesome."
Unfortunately for the happy parents it seems their issues with X Æ A-12 go further than disagreements over pronunciation.
The unusual choice could fall foul of state rules in California, where the couple are based, which stipulate that names can only use the 26 alphabetical characters of the English language.
●stipulate 規定，約定；明確說明
She agreed to buy the car, but stipulated racing tyres and a turbo-powered engine. 她同意買這輛車，但指明要裝賽車輪胎和渦輪動力引擎。

[ + question word ] We have signed a contract which stipulates when the project must be completed. 我們已簽署合同，規定了項目必須完成的時間。
●alphabetical character 字母符號
For those curious about what the name means, Grimes broke down each character of the name in a post on Twitter.
She explained "X" stood for "the unknown variable," while Æ -- AI -- was shorthand for artificial intelligence and translates to "love" in several languages.
The 32-year-old star then shared that a part of her son's name is a reference to the couple's favorite aircraft.
"A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent," she added. Although Musk later corrected his partner, saying it was actually "SR-71."
Grimes concluded the explanatory post on Twitter by revealing that the "A" in the name also represents "Archangel," which she described as her favorite song.
