means A marked path, route, or course for moving along — or the visible mark something leaves behind, or the act of following such marks.

from From Middle Dutch or Middle Low German 'trek,' meaning a drawing or pulling — the same family that gives us 'trek' and 'trace.' The earliest sense was the mark left by something dragged or hauled, like the rut a wheel cuts or the trail a beast leaves. From that drawn line came every later 'track': the railway, the running oval, the song on a record (a groove literally pressed into the disc), and the verb 'to track,' meaning to follow those telltale marks.
