Engine version 1.0 · Breakdown computed from the live checker · Research Desk
Structure
kae from Kaeya, plus luc from Diluc.
Kaeya coverage 60%
Diluc coverage 60%
At the join, el, a vowel meets a consonant, which is the seam that most often survives being read aloud by someone seeing it for the first time.
Why this name is shaped the way it is
Three letters from the front of one name and three from the back of the other. Taking the tail is the less common choice, made here because Dil on its own would read as a word rather than as a name.
What our own engine would have built
Handed Kaeya and Diluc with no knowledge of the fandom, the blender proposes Kaeyluc, Kaeluc, Diluya, Kaeyuc, Dilya, Diya. KaeLuc is among them, which is unusual: most established ship names are not what a structural ranking would pick.
Reading it out loud
The join sits at el, and that is the part worth saying aloud before committing to a name. KaeLuc carries it without trouble, which is a large part of why it stuck: a ship name has to survive being said in a sentence, not only being typed into a tag. It matters more than it sounds. A blend that reads cleanly on a page and stumbles in speech tends to lose to a plainer alternative, however elegant it looked when it was written down.
If you are naming a pairing of your own
The useful lesson from KaeLuc is not the name itself but what it kept. A blend that works holds enough of both halves that a reader who knows Kaeya and Diluc recognises them without being told, and stops there. Taking more from one side than the other is what produces a name that reads as one person rather than two.
If you want to run the same check on a name of your own, the draft checker does exactly what produced the breakdown above, and the ship name generator builds candidates from two names you supply. The method behind the scoring explains what the coverage figures mean and, more importantly, what they cannot tell you.

Questions
What is the ship name for Kaeya and Diluc?
KaeLuc. It is the name the Genshin Impact fandom uses for Kaeya and Diluc as a pairing, and it is what you will see on tags, fan work and video titles about the two of them together.
What does KaeLuc mean?
KaeLuc is the ship name for Kaeya and Diluc from Genshin Impact. A ship name is a nickname for a pairing, and shipping means wanting two characters to be together.
Who is KaeLuc?
KaeLuc is not a person. It refers to Kaeya and Diluc as a pairing, which is how fandom communities talk about two characters together in one word.
How was KaeLuc formed?
By joining kae from Kaeya to luc from Diluc. That keeps 60% of the first name and 60% of the second.
Is KaeLuc the only ship name for Kaeya and Diluc?
No. Two names can be joined in several ways, and from Kaeya and Diluc alone a blender produces Kaeyluc, Kaeluc, Diluya among others. KaeLuc is the one the community settled on, and that is a matter of use rather than of structure: a name becomes the name when enough people tag with it.
Where would I see KaeLuc written?
Mostly as a tag. Ship names exist because writing out Kaeya and Diluc every time is tedious in a tag, a title or a search box, and one word does the same job. You will find it on fan work archives, in video titles, and in the search terms people use when they are looking for work about this pairing specifically rather than about Genshin Impact generally.
Does using KaeLuc mean it is canon?
No, and the two are unrelated. A ship name records that people are interested in Kaeya and Diluc as a pairing. Whether Genshin Impact ever puts them together is a separate question, and some of the most used ship names belong to pairings that never happen in the story at all.
