Tapeline → The word is formed from "tape" (from Old French *tape*, meaning a strip of material) and "line" (from Latin *linea*, meaning a line or string). A tapeline is a strip of material marked with measurements, used for measuring length.
Think of a 'strip of material' ('tape') that has 'measurements' ('line') marked on it — that's what a tapeline is used for.
