The title of the poem is "and an intelligent reader should wonder why a person stops on a snowy evening.So this effect creates curiosity.There is also in the title a trochaic rhythm because of the stressed words :stopping,woods,snowy,evening.

The word stopping invites the reader to think before reading.The poem is arranged into four stanzas and each of them is  made up by four lines.

In the first stanza we can find some figures of sound: for example, in the first line there is the alliteration whose-woods the sound of which creates a kind of surprise in the reader.

Another alliteration is his-house: the sound may reproduces the blow of the wind. In it the poet speaks about a person living in a village who doesn't want to see him.

In the second stanza there is the rhyme near-year that has the function to link  the lines.

Here it is said that the poet's horse may wonder why they may have stopped in a place without a farmhouse, surrounded by woods and a frozen lake.

In the third stanza we can find a sibilant sound ,that is "gives his harness bells",which underlines what the horse does: indeed it is trying to heat up. This stanza is one where the sound aspect turns out really relevant , because here the sounds heard by the poet is described carefully for example that of the wind. There is also a metonimy,  flake stays in fact for the snow. This underlines the fall of the snow ina dark evening.

In the last stanza there is an anaphoric repetition to focus the reader's attention on what the poet has or will have to do.

In it the poet says that he would like to stay and see the woods but he must go because he has something to do before sleeping "forever".

But there is also a connotative meaning that can be inferred inferred in the poem.

I think that the poet wants to tell us that in our life there are some moments when we must stop because we want or we are forced to.

In addition we can understand how the beauty of a moment is given by its short length like stopping to admire the silence of a wood filled up with snow.

And then we leave again because we must go  back to those who are waiting for us.
