Pronunciation: [nˈiːvəs] (IPA) 
The word "Naevus" is a medical term used to describe a birthmark or mole. Its spelling may seem confusing, but it can be broken down phonetically as "nay-vus." The "ae" in the word is pronounced as a long "a" sound, like in the word "day." The "v" is pronounced as a "v" sound, and the "u" is pronounced as a "u" sound, as in the word "put." Remembering this phonetic breakdown can help one correctly spell and pronounce the word "Naevus."
Nevus, also spelled naevus, is a term used in dermatology and pathology to describe a benign (non-cancerous) growth or lesion that appears on the skin or mucous membranes. This dermatological condition can occur at birth (congenital) or develop later in life (acquired). A naevus is commonly known as a mole.
Typically, a nevus appears as a small, pigmented spot or raised bump on the skin, ranging from light to dark brown in color. It is caused by an overgrowth of melanocytes, the cells responsible for producing the pigment melanin. Melanin gives color to the skin, hair, and eyes. While most nevi are harmless and do not require treatment, some may be associated with increased risks of developing skin cancer, especially if they exhibit atypical or unusual characteristics.
There are different types of nevi, including intradermal nevi, compound nevi, junctional nevi, blue nevi, and spitz nevi, each with specific features and appearances. Monitoring and regular examination of nevi is crucial, particularly if any changes in size, shape, color, or texture are noted, as these might indicate potential malignancy.
In conclusion, a naevus is a benign growth or lesion on the skin, often referred to as a mole. While many nevi are harmless, a healthcare professional should evaluate any changes in appearance or suspicious qualities, as some nevi may pose a risk for skin cancer.
A permanent natural spot or mark on the skin at birth; a birth-mark.

The word "naevus" comes from Latin, specifically from the word "nāvus", which means "mole" or "birthmark". This Latin term itself is derived from the Proto-Indo-European root *neh₂- ("cloud, fog"), which also gave rise to words like "nimbus" and "nebula" in Latin, as well as "néphos" in Greek, all of which reference clouds or mist-like formations. The connection between this root and the word "naevus" may be due to the resemblance between certain moles or birthmarks and the appearance of clouds or blotches on the skin.
