Here's an example of a rhyming metaphor:
_"Love is a rose, a thorny bliss;
A joy to behold, a pain to kiss."_
This rhyming metaphor compares love to a rose, drawing a parallel between the beauty and thorns of the flower and the pleasure and pain that can be associated with love. The repeated "S" sound in "rose" and "bliss" as well as "behold" and "kiss" enhances the poetic effect of the metaphor.
Rhyming metaphors can add a layer of complexity and depth to a literary work by evoking multiple levels of meaning and interpretation. They can also serve as a mnemonic device, making the metaphor easier to remember and recall.
