a bounded stretch of land: a region, the countryside, or a field, with the scale set by context
At its heart this word simply names a stretch of land marked off from what surrounds it. What kind of stretch depends entirely on the scene. Zoomed out, it is a whole region or country, often named after the people or the ruler who hold it, like the country of the Gadarenes or the far country a runaway son escapes to. Zoomed in, it is the open countryside as opposed to a walled city, or even a single farmer's field ripe for harvest.
The senses shade into one another rather than standing apart, because they are one idea seen at different scales. The same word can mark the land a king's household draws its food from, the fields a hired hand mows, and the dry shore that sailors strain to reach in the dark. Only the surrounding words tell you how wide to draw the boundary.
Because English keeps separate words for country, countryside, and field, a translator must pick one each time, and the single thread that runs through all of them, a defined piece of ground, can quietly drop out of view.
