About This Root
From Latin līnea (linen thread, string, line), from līnum (flax). In English it covers geometry (linear, delineate), ancestry (lineage, lineal, patrilineal), and infrastructure (airline, pipeline, guideline, streamline, outline). The progression from a physical thread to abstract lines and lineages is a natural metaphorical extension.
