The word "incisure" (noun) refers to a furrow or notch, particularly the V-shaped cut that can be observed on the edge of leaves. The IPA phonetic transcription for this word is /ɪnˈsɪʒə/, which starts with the "ih" sound (as in "sit") followed by "n" and "s" sounds, and ends with "zh" (as in "pleasure") and "uh" sounds. The word is derived from the Latin word "incisura," meaning "a cut or incision," and is often used in biology and medicine.
An incisure is a noun that refers to a notch, slit, or indentation found on a surface, particularly in anatomy or natural formations. It is commonly observed in various biological structures, such as bones, teeth, and organisms. In medical terms, an incisure often describes a junction or division in an organ or tissue.
In anatomy, the term incisure is frequently used to describe specific anatomical features present in the human body. For instance, the incisura is a small indentation located on the lower margin of the stomach. This feature divides the stomach into two main sections, the fundus and the body. Furthermore, the cranial incisura is a prominent structure found in the skull. It refers to the hollow indentation at the base of the skull where the spinal cord connects to the brain.
Natural formations can also exhibit incisures, such as the incisura of a valley. In geology, an incisura is a deep cleft or gorge caused by erosion, typically formed by a river or stream over time. This process carves out a valley with a distinct V-shaped notch, creating a prominent incisure in the landscape.
In summary, an incisure is a term used to describe notches, slits, or indentations, often found in anatomical structures or natural formations. Its application spans across various scientific disciplines, including anatomy and geology.

The word "incisure" has its roots in Latin. It stems from the Latin noun "incīsus", which is the past participle of the verb "incīdō", meaning "to cut into" or "to make an incision". The term entered the English language in the mid-17th century, originally referring to a small incision or notch made in surgery or anatomy. Later, it also came to describe a cleft or indentation found in various other contexts, such as in botany or typography.
