Portmanteau, blend, meshing: what to call it
Engine version 1.0 · Research Desk · Last updated August 2026
Combining two names into one word is called a portmanteau, or equivalently a blend. Applied to personal names it is name blending; applied to surnames in a marriage it is often called meshing; in fandom the result is a ship name and in everyday use a couple name. They all describe the same operation.
People arrive at this site searching for every one of those words, plus mashup, smoosh and name mixer, and often unsure whether they are the same thing. They are. What follows is the vocabulary, and then the part that actually matters: where the two names get cut.
Portmanteau
A single word made by fusing parts of two words. The oldest and most general term, borrowed from literary criticism, and the one most people reach for when they want to sound precise. Smog from smoke and fog is the standard textbook example.
Blend
The plain linguistic term for the same operation. Linguists tend to say blend where everyone else says portmanteau, and there is no meaningful difference in what is being described.
Name blending
Blending applied specifically to personal names. This is the umbrella term for what this whole site does, whether the result is for a couple, a pairing, a baby or a business.
Name meshing
Blending applied specifically to surnames, usually by two people deciding on a shared family name. The word is used almost exclusively in the marriage context.
Ship name
The fandom term for the blended name of a pairing. It carries meaning the other terms do not: a ship name implies a community that uses it, not just a word somebody built.
Couple name
The everyday, non-fandom term for the same thing. Brangelina is a couple name; Percabeth is a ship name; both are portmanteaus of two personal names.
Mashup, smoosh, name mixer
Informal words for the same operation, common in tool names and search queries. None of them mean anything different, and none of them are wrong.
The part the vocabulary hides
All those words describe the result. None of them describe the decision that actually determines whether a blend works, which is where each name gets cut.
A blend takes the front of one word and the back of the other. The front and back are not arbitrary: they are bounded by the points where a word naturally comes apart, which for a name means its syllable boundaries. Cut there and the fragment still carries identity. Cut anywhere else and you get a piece nobody can trace back to anything.
Our engine finds those points by walking the name and marking a split after each vowel group and after each consonant that follows it. Run on olivia, it returns split points at 1, 2, 3, 4, so the openings available are o, ol, oli, oliv. Every one of those is a piece a reader can still recognise; the pieces between them are not.
That rule is documented in full on the methodology page, including the parts of it that are judgement calls.
Blends that share a letter
The smoothest blends are the ones where the two names overlap at the seam, so the shared letter does double duty. Katara and Aang meeting on the a is the reason Kataang reads as one word rather than as two stuck together. When an overlap is available, it is almost always the cleanest join, and our engine surfaces those candidates like any other rather than treating them as special.
When it is not a blend at all
Two of the shapes people call ship names are not blends. A trait name is built from what the characters are rather than from their names, and a paired label keeps both names side by side. Neither can be produced or checked by a blending engine, and both are covered in how fandoms decide a ship name.
Common questions
What is it called when you combine two names into one?
The general term is a portmanteau, or equivalently a blend. Applied to personal names it is called name blending; applied to surnames in a marriage it is often called name meshing; in fandom the result is called a ship name and in everyday use a couple name.
Is a ship name a portmanteau?
Usually, but not always. Most ship names are portmanteaus of the two character names. Some are trait names built from what the characters are rather than what they are called, and those are not portmanteaus at all.
What is the difference between a portmanteau and a compound word?
A compound joins two whole words, like bookshop. A portmanteau overlaps or truncates them so that at least one loses part of itself, like brunch from breakfast and lunch. Name blends are almost always the second kind.
Is name meshing the same as hyphenating?
No. Hyphenating keeps both surnames intact and joins them with a hyphen. Meshing fuses them into a single new word, so both names give something up. They are different decisions with different paperwork.
