Step-by-step explanation:
The poetic device used in the phrase 'Cloud-like hair' is a simile.
A simile is a figure of speech that makes a comparison, showing similarities between two different things. In this case, the writer is comparing the appearance of hair to a cloud, likely suggesting that it's soft, fluffy, or airy. Similes are often introduced by words 'like' or 'as'.
On the other hand, a metaphor directly states a comparison ('Her hair is a cloud'), while personification gives human qualities to non-human entities, and alliteration is a repetition of the same consonant sounds at the beginning of words in a sentence or line.
