(“This form of words seems to mean something but means nothing”. That is: We connect a certain image with this expression or we are inclined to use it because it sounds analogous to other expressions & we connect a certain attitude, state of mind etc. with it; but if we then ask ourselves how we are going to use it we find that we have no use for it or a use of a totally different kind from that, which we at first vaguely imagined (expected).)
