You are not able to delete a word using the BACKSPACE key because the BACKSPACE key does not work in the vi editor.
Key Takeaway: By default, vi does not support the BACKSPACE key in insert mode. It could erase only the characters entered in this instance of insert mode. To erase previously-entered characters in insert mode using the backspace key, use the: set backspace=indent,eol,start command.
