This question already has an answer here:
According to Wikipedia, "A mondegreen is a mishearing or misinterpretation of a phrase as a result of near-homophony, in a way that gives it a new meaning"
"Mondegreen" is also an example of a mondegreen, because it is a mishearing of "laid him on the green"
My question is this: Is there a word for this? That is, is there a word that describes the phenomenon of a word being an example of what it is? Are there other instances of this?
To provide an analogous example, onomatopoeia characterizes a word which sounds like the sound it describes (ex, boom, chirp).
This question, thought related, is different, I think.
