Why might the poet have chosen to use a lack of punctuation marks in ‘Climbing My Grandfather’?

To create a sense of continuity and faster pace in this climb that is 'free'; he climbs up higher on his grandfather without stopping, exploring their relationship deeper and deeper. The continuity could also show how although his grandfather ages, like the mountain central motif suggests, he will never die because he lives in memory.

The lack of punctuation marks, can be define by a technique. This is a Atypical syntax, this is where the lack of/and or over use of punctuation creates a structural effect. In the case of "Climbing My Grandfather" the lack of punctuation creates a overwhelming effect for the reader, it represents who the writer is blurting down all of his emotions, in order to convey his overwhelming wave of emotions. It can also reflect the movement of him on his Grandfather's back as unstable, when one is tired from exhaustion they tend to blurt their sentences, this can be reflected in the lack of punctuation marks used in this poem.
