Question

What does the speaker mean by blue finger in vagond?

Answer 1

In this poem, the phrase “blue finger” is an example of synecdoche; the part (finger) is being used to represent the whole (the whole person). The speaker tells us that autumn is “silencing” a bird and “biting” the finger as a way of telling us that the cold is very strong. Using “autumn” to mean “cold” is another example of synecdoche: this time the whole (autumn) is being used to refer to one of its aspects (coldness). Synecdoche is a figurative technique in which a part is used to refer to the whole or the whole is used to refer to a part. I have included a link to the dictionary definition of synecdoche.
