Learning compound words alphabetically is a simple way to stay organised. When you study one letter at a time, you meet a manageable group of words, you can track your progress and you can see how many you already know. This quiz focuses on compound words starting with M that are useful in conversation, at school and in exams, including Mailbox (A box that receives letters), Makeup (Cosmetics applied to the face), Makeover (A complete change of appearance), Makeshift (Used as a temporary substitute), Marketplace (An open area where people trade), Markdown (A reduction in price).
There are fewer common compound words that begin with M than there are ordinary words, so this page offers 20 questions instead of a full fifty. Every compound word included here is genuine, current English that is worth learning.
Most compound words here belong to daily life: bedrooms, cupcakes, playgrounds. Knowing them makes storybooks, films and conversation far easier to follow.
Compound words fill the texts you read every day. Spotting them quickly speeds up reading, and using them correctly makes your writing sound natural and precise.
Cambridge, IELTS and TOEFL materials recycle the same high-frequency compound words again and again. Practising by letter gives you steady, focused revision.
A compound word is created when two whole words join to form a single new word with a meaning of its own. Sun + flower gives sunflower, tooth + brush gives toothbrush, and rain + bow gives rainbow. The joined word is not just the two parts side by side: a greenhouse is a glass building for growing plants, not a house painted green. Because each compound works as one unit, you should learn it the way you learn a single new word.
Compound words are everywhere in English. We eat pancakes for breakfast, type on a keyboard, watch a sunset and carry a backpack. Once you start noticing them, you will see them on every page, and knowing the two roots inside a long word is one of the fastest ways to guess the meaning of vocabulary you have never met before.
| Compound word | Built from | Example sentence |
|---|---|---|
| Sunflower | sun + flower | The sunflower turned towards the light. |
| Toothbrush | tooth + brush | Pack your toothbrush for the trip. |
| Rainbow | rain + bow | A rainbow appeared after the storm. |
| Ice cream | ice + cream (open) | We shared an ice cream on the pier. |
Compound words reach the page in three different shapes. Knowing the forms helps you spell them correctly and recognise them instantly while reading.
The two words fuse into one, with no space at all: notebook, bedroom, sunflower, airport. Most modern compounds end up here.
A hyphen links the two parts: mother-in-law, X-ray, check-in. Hyphens often appear when two vowels would collide or the meaning needs clarity.
A space stays between the parts, but the pair acts as one idea: ice cream, post office, high school. English slowly closes many of these — web site became website.
When you learn a new compound, note its form at the same time. Write the whole compound, its two roots and one example sentence on a single line of your notebook.
When two options both look possible, work through these steps before you answer.
English builds compound words in families. One small root joins dozens of partners, and each partner keeps a piece of the root meaning with it. Learn the root once and you get every compound in the family almost for free. Treat these patterns as clues, not laws — and always learn the whole compound, never the root alone.
| Root | Example 1 | Example 2 | Example 3 |
|---|---|---|---|
| air | airplane → a vehicle that flies | airport → where planes land | airmail → letters sent by plane |
| book | bookcase → shelves for books | bookmark → saves your place | bookstore → a shop of books |
| sun | sunrise → the sun comes up | sunflower → tall yellow flower | sunglasses → dark glasses |
| water | waterfall → water falling down | waterproof → keeps water out | watermelon → large juicy fruit |
| home | homework → school tasks at home | homeland → country of birth | housework → jobs in the house |
| fire | fireplace → a place for a fire | firefly → a beetle that glows | firefighter → puts out fires |
| foot | football → game with a ball | footpath → path for walkers | footprint → the mark of a foot |
| hand | handbag → bag carried by hand | handshake → greeting with hands | handwriting → writing with a pen |
| night | nightmare → a frightening dream | nightfall → darkness begins | nightlife → evening entertainment |
| time | timeline → events in order | timetable → plan of times | lunchtime → the hour of lunch |
Compound words appear in every major English exam. IELTS and TOEFL hide them inside listening conversations and reading passages; Cambridge B2 First and C1 Advanced test them directly in Use of English and word formation tasks; school tests love the compounds of home, travel and technology.
Fifteen to twenty minutes a day is enough. Follow this plan, then move on to the next letter.
Teachers, tutors and parents can turn this letter quiz into a longer learning session with these simple ideas.
Write first roots on one set of cards and second roots on another. Students race to build real compound words, then explain each meaning in a sentence.
A student acts out a compound word such as football or hairdryer while the class guesses. Acting the meaning makes it stick.
Open this page on a projector, split the class into teams and award a point for each correct answer. The sticky score bar makes tracking easy.
Focus on one root each week. Collect every M compound word that uses it and build a growing wall chart.
This page has 20 questions, all on one page and split into 2 sets of up to 10. Each question shows one compound word that starts with M and four possible meanings; you choose the correct one.
Only a limited number of common compound words begin with M. Instead of filling the quiz with rare or invented words, this page includes 20 genuine compound words that are worth learning.
Compound words you will practise here include Mailbox (A box that receives letters), Makeup (Cosmetics applied to the face), Makeover (A complete change of appearance), Makeshift (Used as a temporary substitute), Marketplace (An open area where people trade), Markdown (A reduction in price), and many more. Each one appears often in storybooks, school texts, everyday reading and exams, so learning it pays off immediately.
A compound word is made when two whole words join to form one new word with its own meaning. Sun and flower join to make sunflower, tooth and brush make toothbrush, and out and side make outside. The joined word often means something more than the two parts alone, which is exactly why compound words deserve their own practice.
Closed compounds join with no space: notebook, bedroom, sunflower. Hyphenated compounds join with a hyphen: mother-in-law, X-ray. Open compounds keep a space but work as one idea: ice cream, post office, high school. English slowly closes some open compounds — web site became website — so you will meet all three forms.

Because the meaning is not always the sum of the parts. A greenhouse is a glass building for growing plants, not a house painted green, and a brainstorm is an ideas session, not a storm. Near twins such as notebook and notepad differ by one element. The fix is focused practice, and this quiz gives you exactly that.
School students, English learners and anyone preparing for exams such as IELTS, TOEFL, Cambridge B2 First, C1 Advanced, TOEFL or other competitive tests. Teachers and parents can also use it as a quick classroom or homework activity.
