Analogy (सादृश्यता)

Outline & Learning Goals

By the end of this chapter, you will be able to:

1. Understand what an analogy question really tests.
2. Identify the relationship between a given pair of words.
3. Classify analogies into standard types (synonym, antonym, part-whole, tool-work, cause-effect, etc.).
4. Apply a fixed 3-step method to solve any analogy in seconds.
5. Spot and avoid the examiner's favourite traps.

1. The Hook: You Already Solve Analogies Every Day

"Doctor is to patient as teacher is to ______?"

You answered *student* in less than a second — without any coaching. That is the whole game of Analogy. The exam does not test your vocabulary alone; it tests whether you can find the hidden bridge between two words and build the *same bridge* between two other words.

Think of it like this: an analogy is a relationship-matching machine. Two words go in, one relationship comes out. Your job is to find another pair with the identical relationship.

2. The Common Struggle (And Why It Happens)

Most students lose marks in Analogy not because the question is hard, but because:

• They match the words instead of the relationship.
• They stop at the first option that "feels right" — and examiners design exactly such tempting options.
• They ignore the direction of the relationship (e.g., "egg → bird" is not the same as "bird → egg").

Remember: relationship first, words later.

🧠 Active Recall: In "Doctor : Patient :: Teacher : ?", what exactly is being matched — the words or the relationship? Say it aloud before reading further.

3. The 3-Step Method (Your Formula)

For every analogy question, follow these three steps — never skip Step 1:

Step 1 — Make a sentence. Connect the given pair in a short sentence.
Example: *Knife : Cut* → "A knife is used to cut."

Step 2 — Apply the same sentence to each option.

• (a) Pen : Write → "A pen is used to write." ✔
• (b) Paper : Book → "A paper is used to book." ✘

Step 3 — Check direction and exactness. Tool → work, not work → tool. Whole → part, not part → whole. The closest, most precise match wins.

🧠 Active Recall: Try it: *Bird : Nest :: Lion : ?* Make the sentence first — "A bird lives in a nest." Now which option fits the same sentence?

4. Standard Types of Analogies (The Examiner's Menu)

Almost every exam question falls into one of these types:

🧠 Active Recall: Cover the table. Name any five types with one example each. Then check.

5. A Mnemonic to Remember the Types

"SAPTACAD" — a quick memory hook for the most frequent types:

• S – Synonym / Antonym
• A – Animal (young one, dwelling, sound)
• P – Part–Whole
• T – Tool–Work
• A – Action–Cause–Effect
• C – Country–Capital–Currency
• A – Academic study (Cardiology : Heart)
• D – Degree of intensity (Warm : Hot)

If you can run through SAPTACAD mentally, you can classify most exam analogies in under 10 seconds.

6. Worked Examples

Example 1: *Book : Pages :: Wall : ?*

• Sentence: "A book is made of pages."
• Options: (a) Bricks (b) Cement (c) Roof (d) Paint
• "A wall is made of bricks." ✔ → Answer: (a) Bricks
• Trap check: Cement joins bricks but a wall is not "made of cement" alone — bricks is the exact part-whole match.

Example 2: *Moon : Satellite :: Earth : ?*

• Sentence: "The Moon is a satellite."
• "The Earth is a planet." → Answer: Planet
• Trap: "Sun" is tempting (both are in space) but the relationship is *category membership*, not location.

Example 3: *Thermometer : Temperature :: Barometer : ?*

• Sentence: "A thermometer measures temperature."
• "A barometer measures pressure." → Answer: Pressure

🧠 Active Recall: In Example 2, why is "Sun" wrong even though the Sun is related to space? Frame your answer in one line.

7. Direction Matters: The Silent Killer

*Nest : Bird* is not the same as *Bird : Nest*.

• Bird : Nest → creature to its home.
• Nest : Bird → home to its creature.

If the question gives *Nest : Bird*, the answer must also be *home : creature* (e.g., *Hive : Bee*), not *Bee : Hive*. Always read the pair left to right and keep the same order in your answer.

8. Summary Table

📌 Review this chapter after 2 days. Redo the worked examples without looking at the solutions, and recite SAPTACAD once from memory.

⚠️ Caution: Examiner's Trap

Trap 1 — Multiple plausible relationships.
Options are designed so that two of them seem related to the given word. Example: *Doctor : Patient* — options may include both *Teacher : Student* and *Lawyer : Client*. Both look right! The tie-breaker: a doctor treats/cures a patient; a lawyer represents a client, while a teacher teaches a student. Pick the option whose sentence matches *most exactly*. When in doubt, make your sentence more specific.

Trap 2 — Difficult words to confuse you.
Examiners insert uncommon words (*Ornithology, Entomology, Speleology*) so you panic. Don't. The relationship is usually simple — "study of birds", "study of insects". If you know even one common pair of the same type (*Cardiology : Heart*), use it as a template and guess the meaning logically.

Trap 3 — Double-relationship questions.
Some pairs carry two relationships, and only one option matches both. Example: *Apple : Fruit* — options (a) *Mango : Fruit* and (b) *Carrot : Vegetable*. Both fit the first relationship ("X is a Y" — category membership). Now look for the second hidden relationship: in the question pair, the first word is a *specific item* and the second is its *category*, and the item belongs to the plant/food group in the same way. Here both options still tie on category — so sharpen further: an apple grows on a tree and is eaten as a fruit, and so does a mango; a carrot is a root vegetable. The item-to-category match that preserves the *same sub-type* (tree-grown fruit) is *Mango : Fruit*. The lesson: if two options fit the first relationship, hunt for a second layer — sub-category, direction, or function — to decide. Never answer after checking only one layer.
