A portmanteau word is a new word made by joining two words, or parts of them, so the new word carries both meanings. You have probably used a few already without noticing.
🌀 The weird part
Take brunch. It sounds like a word of its own, but it is built from two meals: breakfast and lunch. Brunch doesn't keep either word whole. It takes the start of breakfast (br) and the end of lunch (unch), then sticks them together.
Smog works the same way. It is smoke plus fog, with the start of smoke (sm) and the end of fog (og) joined into one word.
So a blend is not two words placed side by side. It is two words cut up and welded together, so the result is shorter and carries both meanings at once.
🧳 Where the name comes from
Portmanteau is a real suitcase word: a travel bag that opens into two halves. The Oxford English Dictionary credits Lewis Carroll as the first to use portmanteau for this kind of word, in Through the Looking-Glass. In the book, Humpty Dumpty explains that his word "slithy" folds two words together: "lithe" and "slimy".
🔍 Blends you probably know
- Brunch: breakfast + lunch
- Smog: smoke + fog
- Motel: motor + hotel
- Sitcom: situation + comedy
- Spork: spoon + fork (an informal word)
- Chortle: probably snort + chuckle. Carroll's word is often linked to this blend, but the "probably" is important.
⚠️ Common mistakes
Blend or compound? A blend cuts parts off the words.
❌ Sunflower is a blend, because it joins sun and flower.
✅ Sunflower is a compound: both words stay whole. Smog is the blend.
Not a blend. A contraction shortens two words, but it does not cut and join them into a new word.
❌ Don't is a portmanteau word.
✅ Don't is a contraction of do not.
🗣️ Natural examples

The smog over the city hid the hills that morning.

Our favourite sitcom is about a family who runs a bakery.

💬 In a conversation
Ana: Shall we have breakfast at eight?
Ben: Let's do brunch at eleven instead.
Ana: So, a breakfast that waits until lunch?
Ben: Exactly. Two meals, one word.

🥡 The OddLingo takeaway
A portmanteau word is two words sharing one suitcase. The surprising part is how many of them you use every day without noticing. For another name that doesn't match its parts, read Pineapple: No Pine. No Apple. So Why?. For a blend you'll hear in everyday talk, try Hangry: When Hunger Makes You Cross.
