Structure
mer from Merlin, plus rthur from Arthur.
Merlin coverage 50%
Arthur coverage 83%
At the join, rt, two consonants meet, which can build a cluster a reader has to work through.
- A run of three or more consonants, which readers tend to stumble over.
Why this name is shaped the way it is
Mer plus thur, joined on the shared r sound. Both source names are so widely known outside the show that the blend stays readable even to someone who has never seen an episode, which very few ship names manage.
What our own engine would have built
Handed Merlin and Arthur with no knowledge of the fandom, the blender proposes Arthrlin, Merlthur, Merlithur, Merlirthur, Merlihur, Arthurlin. Merthur is not among them. That is the normal result, and it is the clearest illustration of why this site refuses to call any candidate the best one. A community picked Merthur for reasons no software can see.
Reading it out loud
The join sits at rt, and that is the part worth saying aloud before committing to a name. Merthur 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 Merthur is not the name itself but what it kept. A blend that works holds enough of both halves that a reader who knows Merlin and Arthur 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 Merlin and Arthur?
Merthur. It is the name the Merlin fandom uses for Merlin and Arthur 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 Merthur mean?
Merthur is the ship name for Merlin and Arthur from Merlin. A ship name is a nickname for a pairing, and shipping means wanting two characters to be together.
Who is Merthur?
Merthur is not a person. It refers to Merlin and Arthur as a pairing, which is how fandom communities talk about two characters together in one word.
How was Merthur formed?
By joining mer from Merlin to rthur from Arthur. That keeps 50% of the first name and 83% of the second.
Is Merthur the only ship name for Merlin and Arthur?
No. Two names can be joined in several ways, and from Merlin and Arthur alone a blender produces Arthrlin, Merlthur, Merlithur among others. Merthur 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 Merthur written?
Mostly as a tag. Ship names exist because writing out Merlin and Arthur 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 Merlin generally.
Does using Merthur mean it is canon?
No, and the two are unrelated. A ship name records that people are interested in Merlin and Arthur as a pairing. Whether Merlin 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.
