Analogy, at its core, is about relationship. You are given one pair that shares a specific relationship — your job is to find the second pair that mirrors that exact relationship. The word comes from the Greek root meaning "proportion," and that proportional thinking is exactly what SSC CGL tests.
Here is a clean way to think about it: if the examiner gives you Cricket : Bat, they have already told you the relationship. Your job is not to think about cricket — it is to extract the underlying logic ("sport : instrument used to play it") and then apply that same logic to Tennis : ?. Once you name the relationship correctly, the answer almost selects itself.
The difficulty comes from two places. First, some pairs admit multiple valid relationships on the surface. Lion : Roar could be "animal : sound it makes" or "predator : aggressive behavior." You have to pick the relationship that is precise enough to eliminate every wrong option. Second, the wrong options are designed to exploit the most common surface-level associations — so if you do not pause to name the relationship, you will pick the distractor.
Think of analogy like a fraction: A/B = C/D. If A : B :: C : D, then the ratio (relationship) between A and B must be identical to the ratio (relationship) between C and D. Your task is to figure out what that "ratio" is and apply it consistently.
One more thing to internalize: in SSC CGL analogy, the relationship is almost always simple, direct, and dictionary-level. They do not hide it behind obscure knowledge. If you find yourself constructing a three-step argument to justify an answer, you are almost certainly overthinking it. The correct relationship can typically be stated in one short sentence.
Once you train your brain to sort every pair into one of eight buckets, you stop reading questions cold and start pattern-matching at speed. Here are the categories with examples:
1. Object : Function (Tool : Action)
The object is used to perform a specific action. Example: Scissors : Cut. The relationship sentence is: "Scissors are used to cut." Apply it: "Hammer is used to ___." Answer: Hit.
2. Habitat / Medium
A living being's natural environment. Example: Fish : Water. Relationship: "Fish lives in water." Apply: "Bird lives in ___." Answer: Air. Note — do not confuse the medium with an associated object. A bird has a nest and lives in a tree, but its natural medium of movement is air.
3. Collective Place / Institution : Content
A place is defined by what it contains. Example: Library : Books. Relationship: "Library contains books as its primary content." Apply: "Museum contains ___." Answer: Artifacts (not visitors, not history — those are associations, not primary contents).
4. Object : Sound / Action
An animal or entity and its characteristic action or sound. Example: Lion : Roar. Relationship: "A lion makes the sound called a roar." Apply: "A cow makes the sound called ___." Answer: Moo.
5. Object / Entity : Associated Place (Part-to-Whole)
Flower : Garden :: Tree : Forest. A flower is found in a garden as a natural collection; a tree is found in a forest. Notice that Branch, Leaf, Root are parts of the tree — they flip the direction. You need the collective place, not the part.
6. Key-Lock / Access Mechanism
Key : Lock :: Password : Account. The key opens the lock; the password unlocks the account. Both are access mechanisms. The distractor "Computer" is where you use the password, not what it unlocks.
7. Celestial / Natural Phenomenon : Time Period
Moon : Night :: Sun : Day. The moon is the dominant celestial body of night; the sun is the dominant celestial body of day. The distractors (Light, Heat, Morning) are properties of the sun, not the time period associated with it.
8. Sport / Game : Equipment
Cricket : Bat :: Tennis : Racket. Equipment is what you use to play. Ball, Net, and Court are associated with tennis, but the bat in the original pair is equipment used to strike — Racket mirrors that exactly.
This is the single most important skill. Most candidates pick answers based on association ("tennis has a net..."). The fast method is this:
Write a bridge sentence for the given pair. Then apply it verbatim.
A : B. Bridge sentence: "A [verb phrase] B."C : ?. Fill in with the same verb phrase.If two options seem to fit, tighten the verb phrase. "Fish moves through water" — now apply: "Bird moves through ___." Now Air wins over Sky, because sky is the location concept, not the medium of movement.
For number pairs like 4 : 16 :: 7 : ?, apply the same bridge-sentence logic:
4² = 16.7² = 49.Common numeric relationships: square, cube, square root, double, triple, difference by a constant, sum of digits, product of digits. Test the simplest operation first.
For figure-based pairs: identify what changes (rotation, reflection, shading, addition/removal of elements, size change). The change in the second pair must be identical in type, magnitude, and direction.
Before looking at the options, write the relationship as a one-sentence bridge: "A [verb] B." Then apply it to C to find D. This prevents option-poisoning — where reading "Ball" first makes you think tennis-ball and pick the wrong answer. Standard method (scan options, justify backward): ~25 seconds per question. Bridge sentence first: ~10 seconds, and you never get poisoned by distractors.
When two options both seem valid, ask: which relationship is tighter (more exclusive)? For Fish : Water :: Bird : ?, both Air and Sky seem fine. Apply the tightening test: "Fish lives inside water as its medium — the relationship is medium of existence, not general location." Air is a medium; Sky is a location concept. This eliminates Sky in 5 seconds. Standard approach (justifying both and guessing): ~30 seconds. Tight vs. Loose test: ~8 seconds.
For institution-content pairs (Library : Books :: Museum : ?), the wrong options are always associations, not contents. Visitors visit, History is a subject, Art is a type — but Artifacts are the physical primary content of a museum, just as Books are the physical primary content of a library. Train yourself to ask: "What does this place contain physically?" not "What do I associate with this place?" This single filter eliminates 2-3 wrong options instantly, dropping solving time from ~20 seconds to ~8 seconds.
Part-to-whole analogies fail candidates because they reverse direction. If the given pair is Flower : Garden (part → whole collection), the answer must also be a whole collection, not another part. When you spot this, immediately eliminate all options that are parts of C. For Tree : ?, eliminate Branch (part), Leaf (part), Root (part) — only Forest (whole collection) remains. Step count: standard 4-step evaluation → 1-step direction check. Saves approximately 15 seconds.
For celestial/time pairs like Moon : Night :: Sun : ?, the distractors are secondary properties (Light, Heat, Morning). The original pair links Moon to the time period it dominates — Night. Apply the same: which time period does the Sun dominate? Day. Morning is a subset of day, not the full time period. Substituting the bridge sentence "X dominates Y [time period]" directly gives Day. Standard method: ~20 seconds. Substitution test: ~7 seconds.
When you see an analogy question in the exam hall, run this four-step decision tree without deviation:
Step 1 — Cover the options. Do not read the options yet. Look only at the given pair A : B.
Step 2 — Write the bridge sentence. State it explicitly, even mentally: "A [specific verb phrase] B." If two possible relationships come to mind, hold both.
Step 3 — Apply to C. Fill in the blank: "C [same verb phrase] ___." What word fits?
Step 4 — Match and verify. Now look at the options. If your answer is there, select it and move on. If it is not, you either named the relationship wrong (go back to Step 2) or the question is testing a nuanced angle (apply the Tight vs. Loose test).
The entire process should take 8-12 seconds for a clean question. If you are past 15 seconds and still unsure, use elimination: cross out any option that cannot logically complete the bridge sentence, then pick the most specific remaining option. Never pick an option because it "sounds related" — it must complete the exact bridge sentence.
Why this question: This is the canonical sport-equipment pair. It tests whether you distinguish between equipment used to play versus other associated objects (ball, court, net).
Solving path: Bridge sentence: "Cricket is played using a Bat as the striking implement." Apply: "Tennis is played using a ___ as the striking implement." Racket. Ball, Net, Court are associated with tennis but none is the striking implement.
Why this question: Habitat/medium analogy. The trap is the nest-tree association most candidates make first.
Solving path: Bridge sentence: "Fish lives and moves through Water as its natural medium." Apply: "Bird lives and moves through ___ as its natural medium." Air. Nest is home, Tree is perch location, Sky is a location concept — none is a medium of movement. Air is.
Why this question: Tool-action pair. Tests whether you pick the action (Hit) or an associated object (Nail) or a result (Build).
Solving path: Bridge sentence: "Scissors are used to Cut [the action they perform]." Apply: "Hammer is used to ___ [the action it performs]." Hit. A hammer hits — it may drive a nail (object) or build something (result) but the direct action is hitting. Match the level: action-to-action.
Why this question: Part-to-whole collective place. Three of the four options are parts of a tree — this is a deliberate direction trap.
Solving path: Bridge sentence: "Flowers are found collectively in a Garden [the collection place]." Apply: "Trees are found collectively in a ___." Forest. Branch, Leaf, Root are parts of a tree — they reverse direction. Forest is the collection place. Direction lock applied in one step.
Why this question: Institution-content pair. Tests content (Artifacts) versus associations (Visitors, History) versus category (Art).
Solving path: Bridge sentence: "Library physically contains Books as its primary content." Apply: "Museum physically contains ___ as its primary content." Artifacts. Visitors are users, History is a subject area, Art is too broad and category-level — Artifacts are the physical primary content. Content filter applied directly.
Why this question: Access mechanism pair. The trap is Computer (where you use the password) versus Account (what the password unlocks).
Solving path: Bridge sentence: "A Key opens/unlocks a Lock [the thing it grants access to]." Apply: "A Password opens/unlocks a ___." Account. Computer is the device, Security is the purpose, Login is the process — Account is the specific thing unlocked. Stay at the same level as Lock.
Why this question: Animal-sound pair. One of the cleanest analogy types, but distractors (Bark, Chirp, Hiss) all sound animal-related.
Solving path: Bridge sentence: "A Lion makes the characteristic sound called a Roar." Apply: "A Cow makes the characteristic sound called a ___." Moo. Bark is dog, Chirp is bird/insect, Hiss is snake. One-step factual recall.
Why this question: Celestial body-time period pair. Distractors (Light, Heat, Morning) are properties or subsets of day, testing whether you match the correct category level.
Solving path: Bridge sentence: "Moon is the dominant celestial body visible at Night [time period]." Apply: "Sun is the dominant celestial body visible during ___." Day. Light and Heat are properties of the sun, not time periods. Morning is a subset of Day — always pick the full time period to match the category level of Night.
Picking by association, not by relationship. "Tennis has a ball" is true, but Ball does not mirror Bat in the sport-equipment pair. Always ask what role the given word plays, not what comes to mind first.
Reversing the direction in part-whole pairs. If the given pair goes part → whole (Flower → Garden), the answer must also go part → whole. Branch, Leaf, Root all go whole → part. Identify the direction and lock it before reading options.
Choosing a result instead of an action. For tool pairs (Scissors : Cut :: Hammer : ?), Build is a result, not an action. Match category level — action maps to action.
Confusing medium with location. Air is the medium a bird moves through; Sky is the location it is seen in. These are different relationship types. The given pair determines which one you need.
Picking the subset instead of the category. Morning is a subset of Day. When the given pair anchors on a full time period (Night), the answer must also be a full time period (Day), not a subdivision of it.
Over-complicating to justify a favored option. If you are building a three-step argument ("well, a museum has art, and artifacts are a form of art, and the library's books are a form of literature..."), you are rationalizing. The correct answer requires a one-sentence bridge sentence, applied directly.
