UPSC tests irregular forms frequently.


4️⃣ Advanced Rules of Comparison

(Comparison must be between similar things.)

✔ She is the best candidate.

But:
✔ He is best suited for the job. (no article sometimes in predicate use)


(E) Comparative for Two

When comparing two → use comparative.

5️⃣ “Few / A Few / The Few” (Very Important)

Few → almost none (negative)
A few → some (positive)
The few → whatever small number exists

✔ Few students passed. (almost none)
✔ A few students passed. (some passed)
✔ The few students who passed were rewarded.


6️⃣ “Little / A Little / The Little”

9️⃣ Order of Adjectives (Advanced Rule)

When multiple adjectives come before a noun, follow this order:

Opinion → Size → Age → Shape → Color → Origin → Material → Purpose → Noun

Example:

UPSC rarely tests full sequence but checks logical order.


🔟 Adjectives Used as Nouns

Some adjectives can represent a class of people.
