Pronunciation: [sˈʌltɹɪnəs] (IPA) 
Sultriness is spelled with a "u" after the "l" because the "u" represents the sound /ʌ/, as in "hut" or "cup", which is different from the sound /u/, as in "music" or "Zulu". The "i" in "ness" represents the sound /ɪ/, as in "sit" or "win", rather than the sound /i/, as in "bee" or "beet". This word describes the quality of being oppressively hot and humid, often used to describe a climate or atmosphere.
Sultriness refers to a state or quality of being sultry, which is characterized by extreme heat or humidity that often causes discomfort or an oppressive, stifling atmosphere. The term is commonly used to describe weather conditions, particularly in tropical or subtropical regions, where the combination of high temperature and high levels of moisture in the air can lead to feelings of intense heat, stickiness, and a general lack of freshness.
In a broader context, sultriness can also describe an intense and sensual feeling or atmosphere, often associated with a sense of desire or seduction. This definition is derived from the idea that the discomfort caused by physical heat and humidity can be metaphorically translated into a passionate, erotic or provocative ambiance. Sultriness in this sense suggests an overwhelming sensuality or seductiveness that may result in feelings of attraction, temptation, or arousal. For instance, it can be used to describe the sultriness of a song, a person's gaze, or a particular atmosphere in a space.
Overall, whether used to describe hot and humid weather or evoke a seductive atmosphere, the term sultriness conveys the intensity and discomfort associated with extreme heat or passionate sensations.
The state of being very hot and close.

The word "sultriness" is derived from the adjective "sultry".
The term "sultry" dates back to the Middle English period, around the 14th century, and originally had a different meaning. It originated from the Old English word "soltry", which meant "to burn or glow". Over time, the meaning shifted to describe weather conditions characterized by intense heat and humidity, often accompanied by a feeling of discomfort.
The root of "sultry" can be traced back to the Latin word "sultris", which also meant "hot" or "burning". The Latin term, in turn, likely derived from the verb "sugere", meaning "to suck", as in the sense of drawing moisture out of the air, thus contributing to the sensation of oppressive heat.
