In communication, metaphors are considered to be of what nature?

In communication, metaphors are considered imprecise in nature.

A metaphor compares two unlike things and so carries suggestive, open meaning rather than exact reference.

Calling metaphors precise is wrong because their strength lies in figurative, not literal, accuracy.

Calling them non-symbolic is wrong because a metaphor works entirely through the symbolic transfer of meaning.

Calling them non-reflective is wrong because metaphors invite thought and interpretation.

Their imprecision lets one image stand for many possible meanings.
