Grammar
Why a lovely little old rectangular green French silver whittling knife is correct, and every other order is wrong. With a practice exercise.
Adjective order in English is a rule almost no native speaker can state and almost none ever breaks. Put two or three adjectives before a noun and there is exactly one order that sounds right, and the others sound wrong in a way that is hard to explain.
The order has a name, or at least an acronym: OSASCOMP. Learning it matters for IELTS because getting it wrong is immediately noticeable in both writing and speaking, and it is one of the few grammar rules with almost no exceptions.
OSASCOMP
Eight categories, always in this order, closest to the noun last.
Opinion comes first: lovely, beautiful, terrible, useful. Then size: large, tiny, enormous, little. An opinion is what you think; a size is a fact.
Age: old, new, ancient, modern, ten-year-old. Then shape: round, square, rectangular, oval.
Colour: green, dark blue, crimson. Then origin: French, Asian, northern, Victorian.
Material: silver, wooden, plastic, cotton. Then purpose, which sits closest to the noun: whittling knife, running shoes, sleeping bag.
Opinion, size, age, shape, colour, origin, material, purpose. A lovely little old rectangular green French silver whittling knife uses all eight, and no other order works.
Two or three is natural. More than three sounds like a grammar exercise, and in IELTS writing you would rarely want more than two.
Method
Six points about using it in the test.
Because it is the least factual. A beautiful old house, never an old beautiful house. If one adjective is a judgement, it goes first.
A leather running shoe, not a running leather shoe. The purpose adjective is almost part of the noun.
A cold, wet, miserable day: three opinions or conditions, so commas. A big red car: different categories, so no commas.
Native speakers rarely stack more than three. In an IELTS essay, two well-chosen adjectives read better than four.
Wrong order is instantly audible, and examiners notice it under Grammatical Range and Accuracy.
Unlike most English rules, this one holds. Fixed phrases such as big bad wolf follow a separate sound pattern, but they are rare.
Practice
Choose the correct order.
Opinion · Size · Age · Shape · Colour · Origin · Material · Purpose
Work out which category each adjective belongs to, then put them in that sequence.
1Which is correct?
A big red balloon. Size comes before colour.
2Which is correct?
A lovely old house. Opinion always comes first, because it is the least factual of the adjectives.
3Which is correct?
A black Italian leather jacket. Colour, then origin, then material. Material sits closest to the noun of the three.
4Which is correct?
New running shoes. Purpose always sits directly before the noun, so running cannot move.
5Which is correct?
A small round wooden table. Size, shape, material, in that order.
6Where do commas go?
Both B and C. Different categories take no commas, so a big red car. Adjectives from the same category do, so a cold, wet, miserable day.
That is normal, because native speakers apply this rule without being able to state it. Once you know the sequence it becomes almost automatic.

An acronym for the order of adjectives in English: opinion, size, age, shape, colour, origin, material, purpose. Adjectives always appear in that sequence before a noun.
Yes. Wrong order is immediately noticeable in both writing and speaking, and it is assessed under Grammatical Range and Accuracy.
Two or three at most. More than that sounds like a grammar exercise rather than natural English, and in an essay two well-chosen adjectives read better than four.
When the adjectives come from the same category, such as a cold, wet, miserable day. Adjectives from different categories take no commas: a big red car.
Very few. Fixed phrases such as big bad wolf follow a separate sound pattern, but the rule otherwise holds more reliably than most English rules.
