If we say "Mountains are obstacles" is a specific level metaphor, what is a more abstract, or generic level metaphor that carries the same meaning? For example,
If "mountains are obstacles" is specific, then
"barriers are XXXX" is generic.
In other words, mountain is a more detailed example of barrier, as there can be other barriers, such as a pass, a river, etc. What is the more generic word that can have "obstacle" as its more detailed example?
Thanks a lot.
