Definition: The track or indication marking the route followed by something that has passed, such as the footprints of animal on land or the contrail of an airplane in the sky.

Alright class, settle down and let’s take a look! Today we’re tackling a word – “trails.” The dictionary gave us a pretty good definition, didn't it? Let’s break it down nice and slow. “Trails” means more than just walking paths you see in the woods, you know. It's about showing where something has been. Think of it like this: A track – a line left behind, clear and true, Like animal footprints, shiny with dew. Or a contrail , a streak white and bright, Left by an airplane soaring in flight! It's the indication - a sign, you see, Of a journey taken, for all to decree. So “trails” can be physical, like paths we tread, Or invisible marks, silently spread. Does that make sense? Do you have any questions about what "trails" means and how it’s used? Don't hesitate to raise your hand!
