What does Merge Words do?
Merge Words combines two words into one. Type a first word and a second word, and it shows five merges at once: two portmanteaus (one in each direction), an interleaved mix, and the two words joined end to end in both orders. Each result has its own Copy button.
Type spoon and fork and the first result is spork. Type chill and relax and you get chilax. The results update as you type. Nothing is sent to a server, and there's nothing to sign up for.
People use it to name things: a project, a podcast, a pet, a fantasy town, a band, a couple ("ship names"), or a product that sits between two ideas. Blending two real words gives you a name that's new but still hints at what it means.
How to combine two words into one
- Type your first word in the First word box.
- Type your second word in the Second word box. Results appear as soon as both boxes have text.
- Read the five merges. The two portmanteau rows already try both orders; swapping the words between the boxes only changes the interleaved mix.
- Click Copy next to the one you like.
Worked example. First word smoke, second word fog:
- Portmanteau (1→2): smoog
- Portmanteau (2→1): fooke
- Interleaved: sfmoogke
- Concatenated: smokefog
- Reversed concat: fogsmoke
The real-world blend of these two words is smog. The tool's cut is mechanical, so it gives you smoog, close enough to show the idea, and one letter away from the word English settled on.
How each merge works
Every result follows a fixed rule. Knowing the rule tells you which word to put in which box.
| Result | Rule | spoon + fork |
|---|---|---|
| Portmanteau (1→2) | First half of word 1 + second half of word 2 | spork |
| Portmanteau (2→1) | First half of word 2 + second half of word 1 | fooon |
| Interleaved | One letter from word 1, then one from word 2, and so on | sfpoorokn |
| Concatenated | Word 1 followed by word 2 | spoonfork |
| Reversed concat | Word 2 followed by word 1 | forkspoon |
Where the halves split. When a word has an odd number of letters, the middle letter goes to both halves. The front half of spoon (5 letters) is spo: the first three letters. The back half of a 5-letter word is its last three letters. With 4-letter fork, both halves are two letters, so the back half is rk. That's how spo + rk becomes spork.
Interleaving stops at the end of the first word. The mix walks through word 1 letter by letter and adds the matching letter from word 2 after each one. If word 2 is longer, its extra letters are dropped. fog + smoke interleaves to fsomgo; the ke at the end of smoke never appears. Put the longer word first if you want every letter in the mix.
Case and spaces are kept. The tool trims spaces from the start and end of each box but leaves everything else alone, capital letters included. Brad + Angelina gives Brlina and BradAngelina, capitals where you typed them.
Real portmanteaus, and what the tool makes of them
A portmanteau is a word made by blending the sounds and meanings of two others. Lewis Carroll gave the idea its name in Through the Looking-Glass, where Humpty Dumpty explains that "slithy" packs "lithe" and "slimy" into one word, "like a portmanteau," a suitcase that opens into two halves. English is full of them. Here's how the tool's midpoint cut compares with the words people actually adopted:
| Words | Real blend | Portmanteau (1→2) | Portmanteau (2→1) |
|---|---|---|---|
| spoon + fork | spork | spork | fooon |
| chill + relax | chillax | chilax | relill |
| motor + hotel | motel | mottel | hottor |
| breakfast + lunch | brunch | breaknch | lunkfast |
| smoke + fog | smog | smoog | fooke |
| cloud + nine | — | clone | nioud |
The pattern is clear. When both words are short and their halves sound good together, the cut lands on a real word. When one word is long (breakfast), cutting at the middle keeps too much of it. People who coin blends cut where the sounds join smoothly, often at a shared letter or syllable. Motel works because motor and hotel share the -ot- in the middle.
Tip. Treat the results as raw material. Take breaknch, see that it's too long, and trim it by hand to brunch. Or trim the words yourself before you type them: break + lunch gives a 1→2 portmanteau of brench, and br + unch gives a Concatenated result of exactly brunch. Small edits to the input change the cut a lot.
Tips for making a good blended name
- Try both orders. The two portmanteau rows already do this for you. pixel + forge gives pixrge one way and forxel the other. Sometimes only one direction is sayable.
- Look for shared letters. Words that share a letter or sound where they meet blend best, like motor and hotel. If your words share nothing, the concatenated version may read better than a blend.
- Say it out loud. A name that looks fine but can't be pronounced won't stick. If you stumble on it, so will everyone else.
- Keep it short. Most blends that caught on are one or two syllables. Shorten long inputs before merging.
- Check that it's free to use. Before you put a blended name on a product, search it, and check the domain and trademark registers in the countries you sell in.
- Use concatenation for compound words. Some combinations don't need blending at all. sun + light concatenates to sunlight; hour + glass gives hourglass.
What Merge Words doesn't do
It merges exactly two words. It doesn't take a third word, and it doesn't join a list of words with a separator; for that, a text joiner or the Case Converter is a better fit. It doesn't hunt for the shared letter where two words overlap, so each portmanteau is cut at the midpoint every time. It doesn't scramble letters at random either: the interleaved mix follows the same pattern for the same input, every time. If you want to rearrange the letters of one word into other words, use the Anagram Solver.
For more naming raw material, the Random Word Generator hands you words to feed in, and the Username Generator builds handles from scratch. Check the length of your final pick with the Character Counter if it needs to fit a username or domain limit.
Frequently asked questions
How do I merge two words together?
Type one word in each box. Merge Words shows five results at once: two portmanteaus, an interleaved mix, and both words joined end to end in each order. Click Copy next to the one you want.
What is a word made from two words called?
A blend that keeps part of each word, like brunch or spork, is a portmanteau. Two whole words joined together, like sunlight or hourglass, is a compound word. Merge Words makes both.
Why doesn't the tool give me "brunch" from breakfast and lunch?
The portmanteau rule cuts each word at its midpoint. Half of breakfast is break, so the result is breaknch. People who coined brunch cut at the sound instead. Use the result as a starting point and trim it, or shorten the words before merging: br + unch concatenates to brunch.
Why are some letters missing from the interleaved result?
The interleaved mix runs for as many letters as the first word has. If the second word is longer, its extra letters are left off. Put the longer word in the first box to keep every letter.
Can I merge more than two words?
Not in one go. Merge two words, copy the result, then merge it with the third word.
Does it work with names and other languages?
Yes. It works on any letters you type, accented ones included, and keeps your capital letters. That makes it handy for couple names: Brad + Angelina gives Brlina and Angead, which also shows why famous couple names usually get trimmed by hand.
