Compound Words
What you'll learn
- A compound word is made by joining two smaller words together (sun + flower = sunflower).
- The meaning of a compound word is often related to the meaning of its two parts.
- Compound words can be written as one word (sunflower), joined with a hyphen, or as two separate words — in Class 4 we focus on the joined form.
Key concepts
Level 1 — Building compound words
| Word 1 | Word 2 | Compound word |
|---|---|---|
| sun | flower | sunflower |
| tooth | brush | toothbrush |
| foot | ball | football |
| note | book | notebook |
| bed | room | bedroom |
Level 2 — Meaning clues
Many compound words hint at their meaning: a butterfly is not made of butter, but the two parts still help you picture and remember the word.
Level 3 — Spotting compound words
Look for two complete words hiding inside one longer word: rain + bow = rainbow, key + board = keyboard.

Common mistakes
| Mistake | Why it happens | Fix |
|---|---|---|
| Thinking 'butterfly' is made of butter | Taking compound words too literally | Learn the actual meaning of the whole word |
| Missing the second word inside a long word | Not breaking the word into parts | Read slowly and look for two complete words |
| Joining any two words | Forgetting the result must make sense | Check the joined word is a real, meaningful word |
