Key Rules
Suffix-Based Identification (The BCS Shortcut)
The fastest way to identify a part of speech in BCS exams is by
suffix:
| Suffix |
Part of Speech |
Examples |
| -tion, -sion, -ment, -ness, -ity, -ance, -ence |
Noun |
education, movement, kindness, ability |
| -ful, -less, -ous, -able, -ible, -ive, -al, -ish |
Adjective |
hopeful, careless, dangerous, readable |
| -ize, -fy, -en |
Verb |
modernize, simplify, strengthen |
| -ly |
Usually Adverb |
quickly, slowly, happily |
WARNING: -ly Words That Are ADJECTIVES (Not Adverbs!)
This is a
top BCS trap. These common -ly words are
adjectives:
- friendly — She is a friendly person. (NOT: She spoke friendly.)
- lovely — What a lovely day!
- lonely — He felt lonely.
- costly — It was a costly mistake.
- cowardly — That was a cowardly act.
- lively — She has a lively personality.
These words have no standard adverb form. We say "in a friendly manner" NOT "friendlily."

Adjective Order Rule (OSASCOMP)
When multiple adjectives appear before a noun, they follow a fixed order:
Opinion → Size → Age → Shape → Color → Origin → Material → Purpose
- A beautiful large old rectangular brown Italian wooden dining table.
- BCS shortcut: O-S-A-S-C-O-M-P (remember: "Oh So A Student Can Order Many Pizzas")
Comparison Trap: "Senior TO" Not "Senior Than"
Words like
senior, junior, superior, inferior, prior, anterior, posterior take
"to" — NEVER "than".
- He is senior to me. ✅
- He is senior than me. ❌
Linking Verb Rule
After linking verbs (is, am, are, was, were, seem, appear, feel, look, taste, smell), use an
adjective, NOT an adverb.
- The food smells good. ✅ (not "well")
- She looks beautiful. ✅ (not "beautifully")
BCS Shortcuts
- See -tion/-ment/-ness? → It's a Noun. Always.
- See -ful/-less/-ous/-able? → It's an Adjective. Always.
- See -ly? → Usually Adverb, BUT check the list of adjective exceptions (friendly, lovely, lonely, costly, cowardly, lively).
- After is/am/are/was/were/seem/feel/look? → Use Adjective, NOT Adverb.
- Comparison with senior/junior/superior/inferior? → Always use "to", never "than".
- "A pride of..." → Lions. Memorize the collective noun list — it appears almost every year.
Solved Examples
Q1. Choose the correct option: "She is very _____ to everyone."
(a) friend (b) friendly (c) friendlily (d) friendship
Answer: (b) friendly
Explanation: After the linking verb "is", we need an adjective. "Friendly" is an adjective (despite ending in -ly). "Friendlily" is not a standard word. "Friend" is a noun. "Friendship" is a noun.*
Q2. Identify the part of speech of the underlined word: "His kindness impressed everyone."
(a) Verb (b) Adjective (c) Adverb (d) Noun
Answer: (d) Noun
Explanation: The suffix -ness always makes a word a noun. Kind (adj) + ness = kindness (noun). It is the subject of the sentence.*
Q3. Fill in the blank: "He is senior _____ me by three years."
(a) than (b) from (c) to (d) of
Answer: (c) to
Explanation: "Senior", "junior", "superior", "inferior", "prior" always take "to" — never "than". This is a Latin-origin comparison rule.*
Q4. Which is the correct adjective order?
(a) a red big ball (b) a big red ball (c) a ball red big (d) a ball big red
Answer: (b) a big red ball
Explanation: Adjective order: Size comes before Color (OSASCOMP rule). "Big" = size, "red" = color. So "big red ball" is correct.*
Q5. "The flowers smell _____." Choose the correct option.
(a) sweetly (b) sweet (c) sweetness (d) sweeten
Answer: (b) sweet
Explanation: "Smell" is used as a linking verb here (describing the flowers, not the action of smelling). After a linking verb, use an adjective (sweet), not an adverb (sweetly).*
Common Mistakes — Watch Out!
- "Friendly" is an ADJECTIVE, not an adverb. Students see -ly and assume adverb. Remember: friendly, lovely, lonely, costly, cowardly, lively are all adjectives.
- After a linking verb (is/am/are/feel/look/smell/taste), use an ADJECTIVE, not an adverb. "She looks beautiful" NOT "She looks beautifully."
- "Senior than" is ALWAYS wrong. Use "senior to." Same for junior, superior, inferior, prior.
- Confusing noun and adjective forms. "Beauty" is a noun, "beautiful" is an adjective. Check suffix: -ty = noun, -ful = adjective.
- Ignoring adjective order. "A wooden large table" is wrong. Size before Material: "A large wooden table."
Question Pattern Recognition
- "Identify the part of speech of X" → Check the suffix first, then check its position in the sentence.
- "Fill in the blank after is/am/are/seem/feel" → You need an adjective, not an adverb.
- "Senior/junior/superior + ___" → Answer is always "to."
- "A ___ of lions/birds/ships" → Collective noun recall question.
- "Choose the correct order of adjectives" → Apply OSASCOMP: Opinion-Size-Age-Shape-Color-Origin-Material-Purpose.
