Difference Between Stench and Odour: 16 MCQs with answers

Odour

Odour is the neutral, general word for any smell. Stench is narrower and always negative, while fragrance and aroma are not the general term described here.

Stench

Stench is reserved for the offensive end of the smell scale — it carries disgust in its meaning.

Odour is the broader term covering all smells, including stenches

Odour is the inclusive term for any detected smell; stench is a subset of odours that are offensive.

The stench of rotting garbage filled the alley.

Stench means a foul, offensive smell, so only rotting garbage fits. The other sentences pair stench with pleasant things, which is a contradiction.

True

An **odour** is any smell detected by the nose, while a **stench** is specifically an offensive, foul-smelling odour.

The same physical smell can be reported neutrally or condemned

The physical smell is identical; the word choice signals the speaker's attitude — neutral reporting versus negative judgement.

Odour — it is strong but not offensive

Intensity alone does not create a stench. Perfume is not offensive, so it is an odour even when strong.

Stench — it is disgusting even though it is mild

Offensiveness, not strength, decides the word. Sewage is foul, so even a mild whiff is a stench.

Because stench already means a foul, offensive smell

The word stench already contains the idea of disgust, so adding 'pleasant' contradicts its built-in meaning.

Odour

Odour is the neutral technical term used for any detectable smell, including odour pollution. Stench is reserved for the offensive end of the scale.

Detection → naming as odour → evaluation → labelling as stench

First the nose detects a smell, then English names it an odour, then the brain evaluates it, and only a strongly negative verdict makes stench appropriate.

I and III only

Statement I is true because stench is a subset of odour. Statement II is false because many odours are not offensive. Statement III is true — offensiveness, not intensity, decides.

Both A and R are true, and R correctly explains A.

Perfume is strong but not offensive, so it is an odour — and the reason it is not a stench is precisely that offensiveness, not strength, decides the word.

The scientist reports the smell neutrally, while the resident condemns it

Both are describing the same physical smell. Odour is the neutral, technical report; stench adds a negative value judgement. Word choice signals attitude.

Odour names the sensory event; stench names the event after a negative verdict

Odour is the neutral label for a detected smell. Stench is applied only after the brain judges the smell as foul and offensive.

The smell is extremely strong and fills the whole street

Strength alone does not force the word stench. A strong but non-offensive smell is still an odour. The other three are genuine reasons to use odour.
