When you use more than one adjective before a noun in English, they must follow a specific natural sequence. Native speakers feel this instinctively; learners need to memorise the pattern. The mnemonic is OSASCOMP:
Opinion → Size → Age → Shape → Colour → Origin → Material → Purpose
The most important rule to remember: Opinion always comes first, and Purpose always comes last (because it behaves almost like a second noun — e.g., a swimming pool, a racing car).
In practice, you rarely use more than 2–3 adjectives. Here are common real examples:
An adjective can sit in two places in a sentence. The position changes the structure but not the meaning — except for a special group of adjectives that can only appear predicatively.
Attributive = the adjective is placed directly before the noun it describes:
It was a difficult decision. → difficult sits before decision
Predicative = the adjective comes after a linking verb (be, look, seem, feel, smell, taste, become, appear):
The decision was difficult. → difficult comes after was
⚠️ The "A-" Exception — predicative only:
A special group of adjectives starting with a- can only be used predicatively — after a verb. You cannot place them before a noun.
This is the most common adjective error at B1 level. The two forms describe two different things — and confusing them produces sentences that are grammatically wrong or accidentally funny.
The key question to always ask is: "Who is causing the feeling, and who is experiencing it?"
The -ing adjective describes the thing, person, or situation that produces the feeling. It is active — it acts on others.
-ing = active / causes feelingThe -ed adjective describes the person who receives or feels the effect. It is passive — it is acted upon.
-ed = passive / feels the effect
English uses prefixes to make adjectives (and some nouns/verbs) negative. The prefix is not random — it is fixed for each word and determined mainly by the word's origin and its first letter. There is one general-purpose prefix (un-) and four specialist prefixes. Mixing them up produces errors that a native speaker would immediately notice.
⚠️ You cannot freely swap these — unpolite, inresponsible, dislogical are all wrong. Each word has one correct prefix only.
| Prefix | Meaning | When to use it | Bulgarian equivalent |
|---|---|---|---|
| un- | not / reverse of | Default — use for most adjectives; Germanic-origin words | не-, без- |
| im- | not | Roots starting with p or m | не- |
| il- | not | Roots starting with l | не- |
| ir- | not | Roots starting with r | не- |
| dis- | not / opposite action | Latin-origin roots; also used with verbs and nouns | не-, раз- |
| Positive | Negative (prefix) | Bulgarian | Example sentence |
|---|---|---|---|
| happy | unhappy | нещастен | She looked unhappy after the news. |
| comfortable | uncomfortable | неудобен | The chair was uncomfortable. |
| reliable | unreliable | ненадежден | He is completely unreliable. |
| fair | unfair | несправедлив | That rule is unfair. |
| polite | impolite | невъзпитан | It was impolite to interrupt. |
| possible | impossible | невъзможен | It seemed impossible to finish in time. |
| patient | impatient | нетърпелив | He became impatient waiting in the queue. |
| mature | immature | незрял | That reaction was immature. |
| legal | illegal | незаконен | Parking here is illegal. |
| logical | illogical | нелогичен | His argument was completely illogical. |
| legible | illegible | нечетлив | The handwriting was illegible. |
| responsible | irresponsible | безотговорен | Leaving the door open was irresponsible. |
| relevant | irrelevant | неуместен | That comment is irrelevant to the topic. |
| regular | irregular | нередовен | "Go" has an irregular past tense. |
| honest | dishonest | нечестен | It was dishonest to hide the truth. |
| organised | disorganised | неорганизиран | The event was completely disorganised. |
| obedient | disobedient | непослушен | The disobedient student was sent out. |
Not every adjective has a negative prefix form. Some words cannot take any prefix — you must use a different, unrelated word to express the opposite. This is a common exam mistake.
| Word | ❌ Wrong attempt | ✓ Correct opposite | Bulgarian |
|---|---|---|---|
| generous | ~~ungenerous~~ | mean / stingy | скъперник |
| selfish | ~~unselfish~~ (rare) | selfless / generous | себеотрицателен |
| brave | ~~unbrave~~ | cowardly | страхлив |
| kind | ~~unkind~~ is OK, but also | cruel / unkind | жесток |
| stubborn | ~~unstubbborn~~ | flexible / easygoing | гъвкав |
| rude | ~~unrude~~ | polite / respectful | учтив |
Note: unkind is a real English word, but for most of the words above, a prefix form simply does not exist. When in doubt, look it up.
Most adverbs are formed by adding -ly to the adjective. But several spelling shifts apply, and a small group of important words completely break the rule.
| Pattern | Rule | Examples |
|---|---|---|
| standard | + ly | slow → slowly, clear → clearly, quiet → quietly |
| -y ending | drop y, add -ily | happy → happily, angry → angrily, easy → easily |
| -le ending | drop e, add -y | gentle → gently, possible → possibly, terrible → terribly |
| -ic ending | + ally | basic → basically, automatic → automatically |
The Rebels — irregular or zero-change adverbs:
She runs fast.
It was a fast car.
Same form for adj and adv.
He works hard.
⚠️ hardly is a different word — it means "almost not at all" (covered in Rule 6).
She sings well. (not goodly)
⚠️ well can also be a predicative adjective: She feels well.
He arrived late.
⚠️ lately = recently — again, a different word covered in Rule 6.
Adjective-lookalikes — words that cannot take -ly:
Some adjectives already end in -ly: friendly, lovely, lively, elderly, cowardly, orderly. These cannot become adverbs by adding another -ly. Instead, use "in a … way":
These three pairs are the most important adverb distinction at B1 level. In each case, the base form and the -ly form look related but have completely different meanings. Confusing them is one of the most common errors in B1 writing and speaking.
Describes effort or force. How much energy or intensity someone or something uses.
Means almost not / barely. It is a negative adverb — use with positive verbs (not with negatives).
Refers to a specific point in time — arriving or happening after the expected or correct time.
Means recently — over a recent period of time, not a specific moment. Always used with perfect tenses.
Refers to physical or metaphorical closeness in distance. Answers the question "how far away?"
Means almost / not quite. It describes how close you are to completing an action or reaching a number.
