The Eskimo reading is unacceptable because there is at present no interpretive strategy for producing it, no way of "looking" or reading (and remember, all acts of looking or reading are "ways") that would result in the emergence of obviously Eskiri:lO meanings. This does not mean, however, that no such strategy could ever come into play, and it is not difficult to imagine the circumstances under which it would establish itself.
And this is the point.
