Help me to analyze it. Please

[Anna_MAlkovych]

I was given this poem to translate. But before that I need to analyze how the rhyme and stress goes here, but English is not my first, so I just do not get it. If you can, please help me.

The Shape of Nothing Happening

Dust knows the places we have forgotten, or we never see,
marking out the margins of our world: the windowledge’s
cracked paint, the bevelled edges of a doorframe,
the dado rails, the skirting boards, stifling the emphatic
corners of our lives. It fills the gulf behind the sofa,

that small domestic void that stands for losing and forgetting,
or for finding once again. It stands for things
that outlive their necessity, for us busily outliving
ours: particles slow dancing in a shaft of light
shedding the excess that each day we renew.

Its tininess is a feat of scale, but it cannot disapppear.
It is the shape of nothing, the shape of nothing happening,
and of nothing’s impossibility; matter worrying away
at trying not to be, and being all the while; reminding us
there are no absolutes, that all is graded on the scale,

that all is incremental, deciduous, and undecided.

In my opinion, this poem is about opposites and the irony in it. The word "dust" is a means of introducing a concept. "Dust" seems to be measured on a scale, like a thermometer. From Cold to hot and zero to hundered.

Hope I could help.

MineralWater, thanks, that helps a bit. I seem to get what this poem is all about. Still don't get howhe rhymeed it, there is some kind of rythm - I don't know how even to call it, cause I don't seem to get the stcructure.

MineralWater, Forgot to ask, if it is not too much trouble, can you explai - what did he mean saying this : shedding the excess that each day we renew

[Albion]

Everything returns to dust; and dust reminds us that everything decays.
All the things we use or create eventually become discarded or caught in a continuous cycle of decline; but we are constantly adding to the stream with new things.

Nothing (much) is happening because the dust eventually disappears but the currently existing dust is visible within the shaft of light.
The reference to "all" being deciduous is a metaphor for decline taken from trees dropping their leaves in Winter.
I notice that the verse line scheme is 5, 5, 5 +1 but that the first verse is terminated with a comma. I don't think this adds anything to the meaning, however, unless it is to indicate the disorder of our lives.
