Answer:
It makes the speaker sound casual
Explanation:
The use of "cause, a-swimmin, and awesome" by the poet makes her sound casual. A casual text is one that is written in a relaxed tone, and an informal manner. Such a text makes use of everyday language that is easily understood by the reader. As a person reads the poem, "Ode to an Otter", there is a feeling of familiarity and good understanding of what the poet is saying because of her choice of words.
She abbreviated because using 'cause' and always swimming, using 'a-swimmin'. This removes the formality in the poem and makes it informal or casual.
