What is the key feature of metaphors in writing?

Metaphors are a powerful figure of speech prominently utilized in writing and language. The key feature that distinguishes metaphors is their ability to create a comparison between two unlike things without using explicit comparative words such as "like" or "as." This implies a deeper connection and identification between the entities being compared, allowing for more evocative imagery and a richer understanding of the concept being conveyed. For instance, saying "time is a thief" suggests that time stealthily takes away life's moments, imparting a nuanced meaning that goes beyond literal interpretation.

In contrast, the use of "like" or "as" indicates similes, and while exaggeration may create an impactful effect in writing, it does not define the metaphoric structure. Additionally, rhyming phrases pertain to poetic devices that enhance the musical quality of language but do not directly relate to the function of a metaphor in forming comparisons. Understanding this distinction is fundamental in appreciating the creativity and expressiveness that metaphors bring to writing.
