Pronunciation: [stˈaŋk tə hˈa͡ɪ hˈɛvən] (IPA) 
The phrase "stank to high heaven" is a colloquial expression used to describe an intolerable, offensive smell. In IPA phonetic transcription, the word "stank" is spelled /stæŋk/, with the first syllable pronounced as "stang" and the second pronounced as "k." The use of the word "heaven" in the expression may be a reference to a biblical verse that mentions a "sweet-smelling savour" rising to God.
"Stank to high heaven" is an idiomatic expression that describes an extremely strong, offensive, and unpleasant odor that emanates from something or someone. This colloquial phrase is typically used to emphasize just how bad a smell is, emphasizing the intensity and pervasiveness of the unpleasant scent.
The term "stank" refers to the past tense of the word "stink," which means to emit a foul or disagreeable odor. When combined with "high heaven," the phrase intensifies the notion of an overpowering and intrusive smell.
The origin of this expression can be traced back to ancient religious and cultural beliefs in which heaven was considered the epitome of purity and cleanliness. Thus, when something "stank to high heaven," it was perceived as so repugnant that it defied the purity of heaven itself.
Although this idiom can be used literally, it is often employed figuratively to describe situations or individuals with profound negative qualities or characteristics, as if their figurative odor is unbearable. It serves as a vivid and somewhat comical way to convey just how unpleasant or off-putting something is, leaving no doubt in the listener's mind that the subject being referred to is truly repugnant or offensive.
