Pronunciation: [kˈuːlz ˈɒf] (IPA) 
The phrase "cools off" has an interesting spelling, as it includes two consecutive O's. This is because the word "cool" is spelled with a double O to represent the long /u/ sound, while the addition of the suffix "s off" follows the typical English spelling rule of adding -s to create a verb form. In IPA phonetic transcription, "cools off" would be written as /k'ulz ɔf/, with the stress falling on the first syllable of "cools."
Cools off is a phrasal verb that conveys the act of becoming cooler or returning to a lower temperature after previous heating or increasing in intensity. It can also be used to describe the process of decreasing in emotional or physical intensity, usually after experiencing excitement, anger, or exertion.
In a literal sense, when an object or substance cools off, it means that it is losing heat and its temperature is decreasing. This can occur naturally, such as when a hot beverage is left to cool off slowly after being boiled or when a heated metal object is left to cool down. Alternatively, cooling off can be facilitated by intentional actions, such as placing an item in a refrigerator or exposing it to cool air or water.
In a figurative sense, cooling off refers to the reduction or dissipation of intense emotions or heightened states. For example, when someone is extremely angry or agitated, they may be advised to take some time away to cool off, meaning they should calm down or regain composure before further action. Similarly, after engaging in high-energy activities, individuals may need to cool off by resting or engaging in less strenuous activities before returning to normal levels of physical exertion.
Overall, "cools off" is a versatile phrasal verb that can apply to various contexts, involving both literal and figurative cooling, whether it pertains to temperature reduction or the lessening of intensity in emotions or physical activity.
The phrase "cools off" is a combination of two words:
1) Cool: The word "cool" originated from the Old English word "col", which meant "moderately cold" or "neither warm nor cold". It later evolved to mean "mildly cold" or "chilled". The word has been used in English since the 1400s.
2) Off: The word "off" is derived from the Old English word "of", which meant "away" or "from". It has been used in the English language for centuries.
The phrase "cools off" combines the meaning of "cool" (to lower in temperature) with "off" (away or from), indicating a decrease in temperature or the process of becoming less hot.
