Trying to find a singular definition of the word trail can be a daunting prospect.
The Oxford Learner’s Dictionary gives on example: [transitive, intransitive] to pull something behind somebody/something, usually along the ground; to be pulled along in this way. Or to trail something. A jeep trailing a cloud of dust was speeding in my direction. I trailed my hand in the water as the boat moved along. Cambridge English Dictionary gives a different variant: trail definition: a path through a countryside, mountain, or forest area.
That’s just two suggested definitions, with a little research one will find many other varied examples. We have taken artistic licence in including our own definitions that should broadly fit in with acceptable examples, while we also repurposing them to align with the Trail of the Ark parameters.
