I think that this use of lexical repetition helps to give emphasis; when you read it you can hear that the words sound heavy since the word "felled" is formed of just one stressed syllable. In the fourth line we still see the use of alliteration : "fresh and following folded- this time of the letter "f". When the author uses the verb "folded" he refers to the shape of the tree. In the last lines of this stanza, Hopkins remembers the way their "sandalled" shadows "dandled" as if they were bouncing a baby and how they played along the winding bank where river and meadow met. When the author uses the verb "dandled" I get the idea of this child sitting on a tree and this makes me perceive a feeling of protection; he tries to give to the trees human characteristics making it sound protective to express his love for nature and to make the reader understand the importance of these trees. When Hopkins uses the alliteration of the letter "w" describing the river: "wind-wandering weed-winding bank", I get the right impression of the shape of the river. .
In the first line of the second stanza we immediately notice that the author wants to get the readers involved in what he is saying; the "we" Hopkins uses is very significant because the reader gets more interested in reading on. In the eleventh and in he twelfth lines you can see that there is a very strong view from the author about nature and we can see that he loves nature in the way that he hates people that "hack and rack the growing green!" I can clearly notice the two violent verbs Hopkins has decided to use, they make a harsh sound when you pronounce it and the feeling that is transmitted is very negative. In the next two lines Hopkins describes nature as "tender", so as a weak figure. This image reminds me of a woman that is always considered as fragile. In fact Hopkins believes that raping nature is just as bad as raping a woman and it is obvious that even after this that he has a passion, an extreme love for nature.
