I would say that one of the most important words that help to enhance the poem's meaning is in the first stanza. The use of the word "diverge" helps to bring out the critical element of choice that the speaker must speak. The fork in the road, paths which obviously "diverge," helps to convey the sense of incompatibility that the problem of choice often thrusts upon the individual. It is in this setting in which the speaker understands the nature of his decision that is upon him, the true understanding of choice. The use of the term "diverge" is significant because it establishes how choice can tear apart at the individual. This understanding of choice is one in which individuals must seek to reconcile the division that the issue of choice brings upon them. In seeking to find convergence from the point where the roads, "diverge" the speaker begins his analysis. It is for this reason that "diverge" appears in the opening stanza. It reappears in the closing stanza, almost to bring a sense of symmetry to what has been presented. The implication in using the word again is that it is from divergence where convergence must emerge. The issue of choice, its problematic condition, creates divergence, and from this, convergence must become present in order to make sense of our choices and this is what makes "all the difference."
