Pronunciation: [stˈʌnə] (IPA) 
The word "stunner" is spelled with a double "n" in the middle despite the fact that the pronunciation only requires one. This is because of the rule in English that when a suffix is added to a one-syllable word ending in a vowel followed by a consonant, the final consonant is doubled. In this case, the suffix "-er" is added to the word "stun," resulting in the spelling "stunner" with two "n's." Its IPA phonetic transcription is /ˈstʌnər/.
A stunner is a noun that refers to something or someone that is incredibly impressive, stunning, or breathtakingly attractive. It is commonly used to describe a person who is exceptionally beautiful or striking in appearance, often leaving others dazzled or awestruck by their physical attractiveness. A stunner is someone who possesses a unique combination of physical features, charisma, grace, and charm, making them stand out from the crowd.
Additionally, "stunner" can also be used as an adjective to describe an event, action, or thing that leaves people astonished, amazed, or overwhelmed. For example, a stunner of a goal in a sports match or a stunner of a revelation in a book or movie indicates a shocking or surprising moment that leaves a lasting impact on the audience.
The term "stunner" originated from the word "stun," which means to astonish or render someone temporarily unable to think or act due to a powerful impression or shock.

The word "stunner" is derived from the verb "to stun", which comes from the Old English word "stunian". The origin of "stunian" can be traced back to the Old Norse word "stunna", meaning "to make unconscious" or "to daze". Over time, "to stun" developed various meanings such as "to shock", "to amaze", or "to astound". From this verb, the noun "stunner" emerged, referring to something or someone that leaves others amazed, dazzled, or astonished. It is often used to describe an exceptionally beautiful or attractive person. The word has undergone a semantic shift from its original meaning of "causing unconsciousness" to its present connotation of being visually stunning or striking.
