Imagery is the description of an act or anything verbally, giving a visual description of the literal words that were being said. It is a means of providing a visual image or symbolism to words that were said.
The poem "Tattoo" by Gregg Shapiro is about his father's experiences about his time during the Holocaust. The lines <em>"My father won't talk about the numbers"</em> and so on shows his reluctance to re-live the horrific experience of the holocaust. The lines<em> "his bone-crushing hugs"</em> are from the second paragraph of the poem where he, the poet, talks about his father's actions. This is a form of imagery, where the act of the hugging is given a verbal detailed description, allowing the readers to be able to visually imagine the act.
