I heard the illegal poaching being uttered so many times in a TV show, about animals, that my ear of a non-native speaker, made me questioning the validity of the term.
I have made some Ngram research here and looked up _poaching on Wikipedia, but that results haven't given me a satisfactory answer. As a result, I'm still puzzled.
According to Wikipedia, poaching is defined as:
the illegal hunting or capturing of wild animals.
Hence my question: can there be a legal and an illegal poaching?
Please let me know your thoughts on this.
PS: I am familiar with the word poaching since I first watched the movie Robin Hood, starring Kevin Costner, Elizabeth Mastrantonio, Morgan Freeman, etc., almost two decades ago.
