So, it goes to the end of the string with

$, anything before the $ in the regex will be what is captured. Since it wants to remove a word at the end of the string, it uses \w to capture any letter. The + will make it keep on going until it finds whitespace or a symbol. The [.!?] is unneeded, but it just there to make sure it'll match with "Example hello.", "Example hello!" And "Example hello?"
