First Grade English: Compound Words
In the English language, words have the marvelous power to hold hands and combine into brand-new words with entirely fresh meanings. When two complete, independent words join together to create a single new word, they form what linguists call a compound word. In this chapter, you will master the art of identifying, splitting, and building compound words, discovering how two small words create a big, exciting new idea.
What Is a Compound Word?
A compound word is formed when two smaller words are pushed together without any spaces between them to create one unified concept. Both smaller words are complete, meaningful words on their own.

| COMPOUND WORD EQUATION |
+-------------------------------------------------------------+
| |
| Word 1 Word 2 Compound Word |
| |
| [ SUN ] + [ SHINE ] ===> "SUNSHINE" |
| (The star) (Bright glow) (Warm bright light)|
| |
| [ RAIN ] + [ BOW ] ===> "RAINBOW" |
| (Water drops) (Curved arch) (Colors in the sky)|
| |
| [ CUP ] + [ CAKE ] ===> "CUPCAKE" |
| (A vessel) (Baked dessert) (A tiny baked cake)|

The Sum of Two Parts
Notice how the meaning of a compound word is connected to its two parts! A "pancake" is a cake cooked in a flat pan. A "doghouse" is a house built for a dog. A "snowball" is a ball made of packed snow. Looking at the two parts gives you an immediate clue to the meaning of the whole word.

compound Words with Silent Letters and Blends
Notice how compound words can bring together different phonics patterns you have already mastered: "Backpack" has two short vowels protected by "-ck"! "Starfish" pairs the Bossy R (/ar/) with the digraph /sh/! "Snowflake" brings together the vowel team "ow" and the silent e pattern "ake"! Reading compound words is a wonderful celebration of all your phonics tools.
The Compound Word Splitting Strategy
When you see a long word in a book that looks intimidating, look closely: it might just be two friendly little words standing shoulder to shoulder!
+-------------------------------------------------------------+
| THE WORD SPLITTER IN ACTION |
+-------------------------------------------------------------+
| |
| Step 1: Look at the long word: p l a y g r o u n d |
| Step 2: Find the first small word: [ p l a y ] |
| Step 3: Find the second small word: [g r o u n d]
| Step 4: Read word 1: "play" |
| Step 5: Read word 2: "ground" |
| Step 6: Combine smoothly: "PLAYGROUND!" |
| |

No Guessing Required
When you use the splitting strategy, an eight-letter or nine-letter word instantly shrinks into two simple, familiar pieces. You can hold your thumb over the second half while reading the first, then slide your thumb to read the second half!
Compound Words vs. Two Separate Words
Be careful to notice the difference between two separate words and a true compound word. "The sun shines brightly" has two separate words with a space between them ("sun" and "shines"). "The sunshine warmed my face" has one solid compound word without any space ("sunshine"). Compound words are always written as a single unit without finger spaces.
Practice Exercises
Exercise 1: Split each of the following compound words into its two smaller base words: footprint, butterfly, campfire, goldfish, sailboat, mailbox.
Exercise 2: Match each word from List A with a word from List B to build four real compound words: List A: rain, butter, tooth, pop. List B: fly, brush, coat, corn.
Exercise Solutions
Solution to Exercise 1: In "footprint", the two words are "foot" and "print". In "butterfly", the two words are "butter" and "fly". In "campfire", the two words are "camp" and "fire". In "goldfish", the two words are "gold" and "fish". In "sailboat", the two words are "sail" and "boat". In "mailbox", the two words are "mail" and "box".
Solution to Exercise 2: Matching the words yields: "rain" + "coat" = "raincoat"; "butter" + "fly" = "butterfly"; "tooth" + "brush" = "toothbrush"; "pop" + "corn" = "popcorn".
