Part-to-Whole
Analogies
Master the skill of identifying relationships where one term is a component of another: a critical pattern on the SSAT Verbal section.
SSAT Upper Level: Verbal
What Is an Analogy?
An analogy is a comparison between two pairs of words that share the same type of relationship. On the SSAT, you are given one complete pair and must find a second pair that mirrors that relationship exactly.
A is to B as C is to D
The Part-to-Whole Relationship
A part-to-whole analogy connects a smaller component to the larger thing it belongs to. The first word names a piece, and the second word names the complete entity that contains it.
PETAL is to FLOWER as BRICK is to WALL
Visualizing Part Inside Whole
The Core Rule
1
Identify the direction. Is the first word the part or the whole? On the SSAT, part-to-whole means the part comes first.
2
Build a sentence. Use the template: "A _____ is a part of a _____." If it works naturally, you have a part-to-whole relationship.
3
Match the pattern. The correct answer must fit the exact same sentence template with the same logical direction.
Types of Part-to-Whole Relationships
Physical Component
A tangible piece of a tangible object: wheel → car, key → keyboard
Member of a Group
An individual belonging to a collection: player → team, star → constellation
Section of a Whole
A division or segment of a larger structure: chapter → book, verse → poem
Part-to-Whole vs. Type-of
| Part-to-Whole | Type-of (Category) | |
|---|---|---|
| Relationship | A is a component of B | A is a kind of B |
| Example | Wheel → Car | Sedan → Car |
| Test Sentence | "A wheel is part of a car" | "A sedan is a type of car" |
| Key Clue | The part is inside or attached | The word names a subcategory |
Step-by-Step Strategy
1
Read the stem pair. Look at the first two words and ask: "Is one of these a piece of the other?"
2
Build your bridge sentence. Say: "A [first word] is a part of a [second word]." Does it sound right?
3
Eliminate wrong relationship types. Cross out answers that show synonyms, antonyms, cause-effect, or type-of connections.
4
Test the remaining choices. Plug each into the same bridge sentence. The best match wins.
5
Check the direction. Make sure part comes first, whole comes second: the order must match the stem pair.
Example 1: Straightforward
PAGE is to BOOK as _____ is to _____
A) author → novel
Author creates a novel: that is a creator-to-creation relationship, not part-to-whole.
B) room → house ✓
A room is a physical part of a house, just as a page is a physical part of a book.
Example 2: Trickier Choices
STANZA is to POEM as _____ is to _____
A) rhyme → lyric
Rhyme is a feature of lyrics, not a structural section. Wrong relationship.
B) sonnet → poetry
A sonnet is a type of poetry: this is category, not part-to-whole.
C) act → play ✓
An act is a structural division of a play, just as a stanza is a structural division of a poem.
D) drama → theater
Drama is a genre performed in theaters: this is a place association.
Example 3: Advanced Vocabulary
PENINSULA is to CONTINENT as _____ is to _____
A peninsula is a piece of land that is attached to and extends from a larger continent. We need an answer where the first word is a distinct component of the second.
A) bay → ocean ✓
A bay is a section of an ocean partially enclosed by land. This is a part of a larger whole.
B) river → sea
A river flows into a sea. This is a relationship of flow/destination, not part-of.

Common Mistakes to Avoid
✕ Confusing Type-of with Part-of
"Sparrow → bird" is type-of (a sparrow is a kind of bird). "Wing → bird" is part-of. Test your sentence carefully.
✕ Reversing the Direction
If the stem goes part → whole, choosing an answer that goes whole → part is wrong. "Orchestra → musician" reverses the direction.
✕ Picking Loose Associations
"Pencil → homework" feels related, but a pencil is not a part of homework. Stick to genuine component relationships.
Quick Reference Table
| Relationship | Test Sentence | Example |
|---|---|---|
| Part-to-Whole | "A ___ is part of a ___" | petal → flower |
| Whole-to-Part | "A ___ contains a ___" | flower → petal |
| Type-of | "A ___ is a kind of ___" | rose → flower |
| Cause-Effect | "___ leads to ___" | rain → flood |
| Synonym | "___ means the same as ___" | big → large |
Question 1 of 5
FENDER is to CAR as
A fender is a physical component of a car, and a sleeve is a physical component of a shirt. Choice D is a type-of relationship (sedan is a kind of vehicle), not part-to-whole.
Question 2 of 5
SOLDIER is to ARMY as
A soldier is one member of an army, and a singer is one member of a choir. This is a "member to group" relationship. While a battle is part of a war (Choice D), the relationship between a soldier and an army (a person in a group of people) is more precisely matched by a singer in a choir.
Question 3 of 5
PARAGRAPH is to ESSAY as
A paragraph is a structural section of an essay, and a scene is a structural section of a movie. Choice B is creator-to-creation, C is type-of, and D is a tool association.
Question 4 of 5
COUNTY is to STATE as
A county is a defined administrative region within a state, and a neighborhood is a defined area within a city. Both are sections of a larger whole.
Question 5 of 5
VERTEBRA is to SPINE as
A vertebra is one repeating unit that, together with others, forms the spine. A link is one repeating unit that forms a chain. Choice A (bone → skeleton) is also part-to-whole but less precise: a vertebra is a specific repeating component of a spine, just as a link is a specific repeating component of a chain. Choice D is wrong because a rib protects a lung rather than forming part of it.
