The commas act as breaks in the quotation which carries the rhythm of the poem. Link to theme this shows decay as its symbolic when speaking about life fading away during the time of winter.

  5. Key Quotations- the woods that fall, decay and break, the dark comes down, Analysis- The use of the words fall, decay and break give us the idea again of a slow death and the idea of losing power and strength.
