In poetry, as in any other kind of speech, our specific words reveal an enormous amount about us. All languages are rich enough to offer multiple ways of expressing the same sentiment. The poet, it has been claimed, chooses “the best words in the best order.” But what are the “best words”? Since there is no litmus test to determine whether a given word is worthy or unworthy, poets must determine for themselves what vocabulary is appropriate for what work. The results vary widely, depending on the era, the genre, and the personal taste of the individual.
