Leucitic /luːˈsɪtɪk/ is a term used in geology and petrology to describe a type of igneous rock that is poor in feldspar and rich in leucite. The word derives from the Greek word "leukos", which means white, and "lithos", which means stone. The IPA phonetic transcription of the word "leucitic" indicates that it is pronounced as "loo-SIT-ik". This word is a technical term that may not be familiar to everyone outside the field of geology or petrology.
Leucitic is an adjective used to describe the condition of an organism that exhibits leucism. Leucism refers to a genetic mutation that affects an organism's pigmentation, resulting in partial or complete loss of pigments in its skin, feathers, fur, or other parts of its body. As a consequence, the affected individual appears pale or white, lacking the typical coloration of its species.
Leucitic animals may display lighter or whitish tones of their natural colors, giving them a unique and often striking appearance. This condition is different from albinism, where an individual completely lacks pigmentation and usually has red or pink eyes. Whereas albino animals lack all pigment-producing melanocytes, leucitic animals may lack only specific pigments while still producing others. This distinction causes leucitic organisms to retain some coloration in their eyes.
The leucitic trait can occur across various species, including mammals, birds, reptiles, and even plants. It is primarily inherited genetically, but it can also result from environmental factors such as nutritional deficiencies or exposure to toxins. Leucitic individuals may face challenges in their natural habitats, as their altered appearance can make them more vulnerable to predation or reduce their ability to camouflage. However, they can still survive and reproduce if the condition does not severely impact their overall fitness. Lovers of wildlife and nature enthusiasts often find the presence of leucitic animals to be fascinating and captivating due to their distinctive and rare appearances.

The word "leucistic" is derived from the term "leucism". "Leucism" has its roots in the Greek word "leukos", which means "white". Leucism refers to a condition where an animal or bird has reduced pigmentation, resulting in pale or white patches on its feathers, fur, or skin. The suffix "-ic" simply denotes that something is related to or characterized by the condition of leucism. Therefore, "leucistic" describes an organism that exhibits or relates to leucism.
