One of the notable aspects of how Robert Frost constructed the phrase "Something there is that doesn't love a wall" is the use of inversion or poetic syntax. In this line, Frost deliberately deviates from the typical word order found in standard English sentences.
In standard English syntax, the sentence would be structured as "There is something that doesn't love a wall." However, Frost rearranges the word order to create a poetic effect and draw attention to the phrase "something there is."
By using inversion, Frost places emphasis on the word "something" and imbues it with a sense of mystery and ambiguity. This unconventional word order adds a touch of poetic rhythm and helps to capture the reader's attention, emphasizing the idea that there exists an unidentified force or sentiment that opposes the concept of walls.
The construction of the phrase reflects Frost's artistic choice to create a memorable and thought-provoking line that challenges conventional boundaries in both language and ideas.
