2. ANALOGY
• It basically means ‘resemblance of one object to
another in certain aspects.
• It is a way of stating a comparative relationship
between two sets of terms.
• Analogy is established, when the two pairs on
both the sides of the sign (::) bear the same
relationship.
3. EXAMPLE
• kitten : cat :: puppy : dog
-Kitten is to cat as puppy is to dog.
( : ) can be read as ‘is to’
( :: ) can be read as ‘as’
5. 1. PART TO WHOLE
• Perhaps this is the most common kind of analogy
because many analogy examples fit into this
category. These are relationships between things
that compare two sets of objects, both of which are
part and whole pairs.
• Example:
battery : flashlight : : hard drive : computer
Branch : tree :: arm : man
6. 2. CAUSE TO EFFECT
• Cause to effect analogies explore the similarities
between events that cause a variety of effects.
They can be helpful for allowing people to
understand relationships between events.
• Example:
drought : wildfire : : infection : disease
Earthquake : tsunami :: cavity : toothache
7. 3. SOURCE TO PRODUCT
• Analogies that compare sources and products can
be a good way to explain the provenance of
various day-to-day objects. This kind of analogy can
be particularly useful for explaining production
methods to children.
• Example:
Bees : honey : : wood : pencil
Orange : orange juice :: cocoa beans : chocolate
8. 4. OBJECT TO PURPOSE
• This is similar to a cause-and-effect analogy or a
source to product analogy, meaning that it is about
instrumental action. The first word in each half of the
analogy is an object, followed by what that object
is most commonly used for.
• Example:
book : reading : : racket : playing tennis
pencil : writing :: scissor : cutting
9. 5. CHARACTERISTIC (CATEGORY)
• Some common analogies are about characteristics.
The first word in each half of the analogy provides a
characteristic, while the second word provides the
thing that has that characteristic. It is possible to get
quite creative with this kind of analogy.
• Example:
Tropical : hot :: polar : cold
Sky : blue :: grass : green
10. 6. GENERAL TO SPECIFIC
• One way to express analogy relationships is to
focus on things that go from general to specific.
This is similar to the reverse of a part to a whole
analogy.
• Example:
Fish : catfish :: bird : eagle
Fruits : apple :: vegetables : squash
11. 7. USER TO TOOL
• In many cases, people who use particular
tools have specific titles. This can provide
the basis for a user to tool analogy.
• Example:
doctor : stethoscope : : camera operator : camera
carpenter : hammer :: surgeon : scalpel
12. 8. SEQUENCES
• Some logic and intelligence tests include analogy
tests to see if people can understand sequential
relationships between concepts.
• Example:
A : B : : 1 : 2
Infant : child :: adolescent : adult
13. 9. SYNONYMS
• Analogies can also be created out of pairs
of synonyms. This can help show the
relationship between the two pairs of words
and explain that they are comparable.
• Example:
happy : joyful : : angry : furious
start : begin :: raise : lift
14. 10. ANTONYMS
• Just like two pairs of synonyms can create analogy,
so can two pairs of antonyms. This shows that two
pairs of things are functionally opposites.
• Example:
Up : down :: left : right
Fast : slow :: far : near
