What is an analogy?
An analogy is a comparison between two pairs of words. It says that the first pair is connected in the same way as the second pair.
Puppy is to dog as kitten is to cat.
A puppy is a baby dog. A kitten is a baby cat. Both pairs share the same relationship: baby animal and adult animal.
Analogies are like word puzzles. To solve one, you must figure out how the first two words are connected, then find a second pair that is connected the same way. They build vocabulary, logical thinking and reading skills, and they often appear on tests.
How to read an analogy
Analogies are often written in colon notation:
puppy : dog :: kitten : cat
- The single colon ( : ) means "is to".
- The double colon ( :: ) means "as".
Read it aloud: "Puppy is to dog as kitten is to cat."
Common types of analogies
Most analogies use one of these relationships. Learning them makes analogies much easier.
| Relationship | Example | How they connect |
|---|---|---|
| Synonyms | happy : glad :: big : large | same meaning |
| Antonyms | hot : cold :: up : down | opposite meaning |
| Part to whole | page : book :: petal : flower | one is part of the other |
| Tool to job | scissors : cut :: broom : sweep | what the tool is used for |
| Worker to tool | painter : brush :: chef : pot | who uses the tool |
| Worker to place | teacher : school :: doctor : hospital | where the person works |
| Item to category | apple : fruit :: carrot : vegetable | what group it belongs to |
| Young to adult | calf : cow :: cub : bear | baby and grown-up animal |
| Cause to effect | rain : flood :: heat : melt | one causes the other |
| Degree | warm : hot :: cool : cold | a little and a lot |
| Animal to home | bee : hive :: bird : nest | where it lives |
A synonym pair has words that mean the same thing. An antonym pair has opposite words. An item-to-category pair puts something in its group.
How to solve an analogy, step by step
Try this one: glove : hand :: sock : ____
- Look at the first pair. How are glove and hand connected?
- Make a bridge sentence. Say the relationship as a sentence: "A glove is worn on a hand."
- Use the same sentence for the second pair. "A sock is worn on a ____."
- Choose the answer that fits. A sock is worn on a foot.
- Check the order. The words must go in the same order in both pairs.
Bridge sentences are the most useful trick for analogies. Make them specific. "A glove goes with a hand" is too loose. "A glove is worn on a hand" is clear.
Watch the order
Order matters. Look at this one:
bark : dog :: meow : ____
Bridge sentence: "Bark is the sound a dog makes." So: "Meow is the sound a ____ makes." The answer is cat.
If you flip a pair, the analogy breaks. dog : bark :: meow : cat does not match, because the first pair goes animal then sound, and the second goes sound then animal.
Let’s try some examples
- finger : hand :: toe : foot (part to whole)
- fast : slow :: early : late (antonyms)
- pen : write :: knife : cut (tool to job)
- Toronto : Ontario :: Halifax : Nova Scotia (city to province)
- seed : tree :: egg : chicken (what it grows into)
Analogies in writing
Writers use analogies to explain new ideas by comparing them to something familiar. The heart is like a pump. It pushes blood through the body the way a pump pushes water through pipes. This helps the reader understand something hard by linking it to something easy.
Common mistakes
- Choosing a word that is just related. In glove : hand :: sock : ____, the word shoe is related to socks, but it does not fit the bridge sentence.
- Skipping the bridge sentence. Guessing leads to mistakes. Always say the relationship first.
- Mixing up the order. Keep the pattern the same in both pairs.
- Making the bridge sentence too vague. "They go together" fits almost anything.
Try it yourself
Complete each analogy and name the relationship:
- up : down :: in : ____
- wheel : car :: wing : ____
- chick : hen :: lamb : ____
- hammer : nail :: key : ____
- tiny : small :: huge : ____
Answers: out (antonyms), airplane (part to whole), sheep (young to adult), lock (tool to object), large or big (synonyms).
Study tip
Write your own analogies. Pick a relationship from the table and make three new examples. Swap with a friend and solve each other’s puzzles.
Quick recap
- An analogy compares two pairs of words that share the same relationship.
- In colon notation, : means "is to" and :: means "as".
- Make a bridge sentence for the first pair, then use it for the second pair.
- Keep the words in the same order in both pairs.
