Here are two senses of metaphor:
- A metaphor is the expression of an understanding of one concept in terms of another concept, where there is some similarity or correlation between the two.
- A metaphor is the understanding itself of one concept in terms of another.
The following sentences illustrate how the metaphorical understanding of anger-as-fire is expressed:

- That kindled my ire.
- Boy, am I burned up!
