"Dew lap" is a term used to describe the hanging fold of skin on the underside of an animal's neck. The spelling of this word can be confusing due to its pronunciation, which is /ˈdjuːlæp/ in IPA phonetic transcription. The "dew" part of the word is pronounced as the word "due," while the "lap" part is pronounced as it is spelled. The word's origins are from Middle English and Old French, which could explain its unusual spelling and pronunciation.
A dew lap is a term used to describe a loose fold of skin that hangs down from the throat and neck area of certain animals, particularly in large mammals such as cattle, horses, and certain breeds of dogs. It is characterized by a suspensory and fleshy protrusion that typically swings or sways as the animal moves. The dew lap is usually more pronounced in mature individuals and can vary in size and shape between different species and breeds.
This anatomical feature serves various purposes depending on the animal species. In some cases, such as in cattle, the dew lap is believed to aid in heat dissipation by increasing the surface area available for evaporative cooling. It may also have evolved as a fat storage area to provide energy during times of limited food availability. Additionally, the dew lap can act as a protective cushion against injuries and abrasions during territorial disputes or fights with other animals.
In terms of appearance, the dew lap is often seen during certain movements of the animal, such as when it is running or grazing. Due to its size and shape, it may also be associated with certain physical traits typical of particular breeds or species, adding to the distinctive characteristics of an animal.
The word "dew lap" comes from the Middle English word "dewlappe", which can be traced back to the Old English word "dēowlæppa". The term "dēowlæppa" is a compound word composed of "dēaw" (meaning "dew") and "læppa" (meaning "loose skin" or "flap"). The "dew lap" refers to the loose fold of skin hanging down from an animal's throat or neck.
