lineaments

The word 'lineaments' traces its lineage to the Latin lineamentum, meaning a line, feature, or contour, which itself derives from lineare, 'to make straight or to line,' and ultimately from linea, 'a linen thread or string.' This core concept of a drawn line evolved metaphorically to describe the linear outlines that define a face or figure. Over time, the meaning expanded from physical contours to encompass the distinctive features or characteristics of any entity. Thus, the modern abstract sense of 'defining features' retains the original logic of being the fundamental lines that sketch an object's essential form.

Structure: line (line) + a + ment (noun suffix) + s (plural suffix) - line: From Latin linea (a linen thread, string, line), from linum (flax, linen).
