Scholars date this metaphorical usage of madhu to a time very close to the initial composition of the Vedas.
Due to its long history and its widespread usage, chi (along with cun) has also seen metaphorical usages in the Chinese language.
Some examples of metaphorical usage include:
Cannon fodder (metaphorical usage)
In other words "blood" means death - the termination of life - just as it does in ordinary metaphorical usage (see, for instance, Genesis 9:5, 37:26; etc.).
This metaphorical usage of the word is much more common than the application of its literal meaning.
It lacks any understanding of metaphorical usage, euphemism, or idiom.
'foil' is a metaphorical usage, but has long since become a dead metaphor.
This list is categorized superficially, rather than by the actual meanings of the expressions, to stress the metaphorical usage.
