I suppose you could imagine this kind of sentence: (1) The tracker (2) traced (3) the traces, which later on appeared to constitute (4) a track [a path] leading to the suspect, but not a (4b) railway (track) (5) EXTRA: the findings did not correspond, were not coherent [like 'rail']* with the facts. --- Not very stylish, but in Dutch you would have : (1) De speurder [detective, the tracker/tracer ?]/ de spoorzoeker -trace searcher, the tracker ?) (2) opsporen [a person] (track down) -- bespeuren (traced, but meaning: simply note, ...) (3) het spoor, de sporen, (4) het spoor [so: same as 3] > de spoorweg (railway) (5) EXTRA*: sporen met So in English I see 4 parallels out of 5. How about your language? If you use a different word, I'd be pleased to hear about the etymology, or the underlying metaphor at least.
