Etymology: "Oblanceolate" is a botanical term for a leaf shaped like a lance head turned upside down: broadest near the tip and narrowing toward the stalk. It is built from "ob-", a Latin prefix meaning "inverse" or "reversed" (as in "obovate", an egg shape reversed), attached to "lanceolate", which describes a leaf shaped like a lance point. Put together, the word names the reverse of the familiar lance-shaped leaf. The core element traces back to Latin "lancea", a light spear or lance, which gave English "lance" and, through the diminutive "lanceola", the shape-word "lanceolate". Botanists adopted these forms to describe leaves by comparing them to weapons and tools, a habit that filled the plant descriptions of the 18th and 19th centuries with names drawn from everyday objects. The prefix "ob-" was then added to create a precise pairing: the same shape, flipped.
