STRUCTURE & METRIC

Like most of Thom Gunn's poems, "The Hug" doesn't follow any set rhythmic or metric structure, because it is written in free verse. This means that the poem doesn't adhere to a rigid rhyme or meter structure and lacks a consistent structure. Because of the poem's structure, the language flows more naturally and has a sense of natural speech. It allows the reader to get a more real and vivid picture of the poem.

Gunn explored a variety of techniques to create rhythm and structure without relying on traditional rhyme. To convey motion and continuity in "The Hug", Gunn used enjambment, which is the practice of continuing lines without any punctuation or a stop at the conclusion, the verse simply rolls over into the next line. The poem's general rhythm is influenced by the different lengths of the lines, some longer, some shorter. This unstable metrical system can transmit emotional spontaneity and make the reader feel closer to the poem. Even though "The Hug" doesn't follow the traditional metrical or rhythmic framework, Gunn uses alliteration and repetitions as a false sense of rhythmic quality and uses them as the overall rhythmic element. 

Overall, Thom Gunn's use of free verse allowed him to experiment with language and form, while capturing the essence of human existence, making his poetry flow naturally, allowing the reader to experience the poem from a closer perspective.
