Pronunciation: [hˈɛvi djˈuː] (IPA) 
The phrase "heavy dew" is pronounced as /ˈhɛvi/ /djuː/. The word "heavy" is spelled with the letter combination of "h", "e", "a", "v", and "y", which represents the sounds /h/, /ɛ/, /v/, and /i/. The word "dew" is spelled with the letters "d", "e", and "w", which represents the sounds /d/, /juː/, and a silent "w". This phrase refers to a large amount of moisture that collects on surfaces during the night, typically outdoors.
Heavy dew refers to a significant deposition of moisture that accumulates on surfaces, such as grass blades, leaves, and objects outdoors during cool overnight conditions. It is a natural occurrence that takes place when the temperature of the air becomes cooler than the dew point. Dew point is the temperature at which the air becomes saturated, and as a result, the excess humidity condenses into tiny droplets of water on various surfaces. The greater the difference between the air temperature and dew point, the heavier the dew formation.
Heavy dew is commonly observed during clear and calm nights as water vapor in the air begins to condense onto cooler objects. This phenomenon is particularly more pronounced in areas with high humidity levels. The quantity of moisture deposited is generally greater than that produced by light or moderate dew.
The presence of heavy dew can have diverse effects on various elements of the environment. It often contributes to the hydration of plants, providing a supplemental water source during times of inadequate rainfall. It can also facilitate the growth of organisms that rely on water availability, such as fungi and certain insects. Additionally, heavy dew can occasionally lead to slippery conditions on outdoor surfaces, leading to accidents if not accounted for. Overall, heavy dew is a natural process that plays a role in maintaining moisture levels in the environment and serves as a vital component of the Earth's water cycle.
The word "heavy dew" consists of two components: "heavy" and "dew".
The term "heavy" traces back to the Old English word "hefig", which meant weighty or having great physical mass. Over time, it evolved into its current form and retained its meaning of being substantial or significant.
The word "dew" comes from the Old English noun "dēaw", which referred to the moisture that forms overnight on surfaces due to condensation. This term further stems from the Proto-Germanic word "*dawwą".
By combining these two words, we get "heavy dew", which refers to a significant amount of dew that forms on surfaces during the night.
