猿 and 鹿: locations before and after movement
Use monkey and deer examples to distinguish movement relative to trees or woods from remaining in place.
A monkey's movement
猿, read さる, means monkey. 猿が木に登りました。 says that a monkey climbed a tree.
猿が木から降りてきました。 says that a monkey came down from a tree. Distinguish the location roles marked by に and から.
A deer's location
鹿, read しか, means deer. 森の入口に鹿がいます。 says that a deer is at the entrance to the woods.
鹿が森の奥へ走っていきました。 says that a deer ran farther into the woods. 奥へ marks its direction.
Action and a continuing state
猿は木に登ったまま降りてきません。 says that the monkey has climbed the tree and remains there without coming down. The state after climbing continues.
鹿を見ている間に、猿が移動しました。 says that a monkey moved while someone was watching a deer. The observed animal and the moving actor differ.
