From the given options, select the Figure of Speech (Poetic Device) used in the expression:

Laughter holding both her sides.

Personification

The figure of speech used in the expression "Laughter holding both her sides" is personification.

Personification is a figure of speech in which inanimate objects are given human qualities. In this case, laughter is being given the human quality of holding. This creates a sense of laughter as being a physical force that is powerful enough to hold someone's sides.

The other answer choices are incorrect. Simile is a comparison between two things using the words "like" or "as." Metaphor is a comparison between two things without using the words "like" or "as." Apostrophe is a figure of speech in which the speaker addresses an absent or inanimate object. None of these devices are used in the expression "Laughter holding both her sides.".

The word "holding" is being used metaphorically to describe the power of laughter. Laughter is not actually holding someone's sides, but the speaker is using the word to create a sense of the laughter's intensity.
