the word 'tracked' is built upon the simplex noun and verb 'track'. its lineage traces back to the middle english 'trak', borrowed from old french 'trac', which denoted a trace, trail, or footprint. the old french term is thought to have germanic origins, possibly related to middle dutch 'treck', meaning a pull or draft, which in turn connects to the proto-germanic 'trakjaną', to pull. the semantic evolution moved from the physical act of pulling or drawing to the visible mark left behind, and finally to the modern sense of a path, course, or the act of following it. the adjective 'tracked' applies this core concept of leaving or following a trail to describe vehicles, evidence, or multi-layered audio recordings.

this is the past tense and past participle form of the verb 'track', which itself is a simplex word. it is not productively formed from smaller, meaningful morphemes in modern english. the base 'track' originates from the middle english 'trak', likely from old french 'trac', meaning a trace or trail.
