Alliteration is demonstrated as a figure of speech which includes repetition of identical consonant sounds in a line of a poem or phrase. Such a device is employed by the poets more often to create a specific effect like rhythm or mood or to emphasize a particular point by capturing the readers' attention.
In the given excerpt, the words "cold, curt, cuts" illustrate this literary device(alliteration) which repeats the consonant sound 'c' and adding a special rhythmic effect to the poem.
