Final answer:
The phrase "no enemy" in Shakespeare's "Under the Greenwood" is an example of personification, signifying the peace found in nature, opposite to the conflict associated with human enemies and emphasizing the safe haven of the greenwood.
Step-by-step explanation:
The figure of speech in the poem "Under the Greenwood" by William Shakespeare, particularly with the phrase "no enemy," could be a reference to the peace and tranquility found in nature as opposed to the strife and conflict associated with human enemies. Shakespeare often used figurative language to suggest deeper meanings, such as metaphor, personification, or hyperbole. In this case, this phrase may be an example of personification, where the abstract concept of enemy is applied to the natural setting, only to be negated, which emphasizes the safe haven that the greenwood represents.
