lemonshaped

Lemonshaped is an English descriptive adjective used to indicate that an object has the general shape of a lemon. It denotes an elongated, ovoid form with a slightly pointed, tapered end and a broader middle, though exact proportions vary. As a qualitative descriptor, lemonshaped is not a precise geometric category; more exact terms include prolate spheroid and ellipsoid.

Usage spans several fields. In design and product development, lemonshaped describes ergonomically curved handles, bottles, or cases that mimic the fruit’s silhouette. In biology and paleontology, seeds, fruits, or fossil fragments may be described as lemon-shaped when they are elongated and curved rather than perfectly oval. In medicine, the term appears in reference to skull shapes observed in prenatal ultrasound; the “lemon sign” describes a lemon-like contour of the fetal skull that can be associated with neural tube defects.

Notes and terminology. The term is often hyphenated as lemon-shaped, though lemonshaped as a closed compound also appears in some texts. It remains a descriptive, qualitative label rather than a formal mathematical class. See also lemon sign; ellipsoid; prolate spheroid; ovoid.
