Language morphs and I accept that the popular definitions of words are generally the ones to work with.
WTS is known for using obscure definitions of words.
There is a group of creationists who believe in the 7 literal days of creation, but in Christian lands like the United States, a creationist is someone who believes that the universe and living organisms originate from specific acts of divine creation described in the biblical account , rather than by natural processes such as evolution.
Yes, JW's have a slightly different view of the biblical account, but most sects do the same.
JW's are so silly in their re-defining. Example: Their leaders are not "inspired" but are "spirit-directed." That means they are everything that "inspired" means but are allowed to change their minds.
