Note 193 — Chapter XIX · RISE OF WORD-FORMATION AND INFLECTION.
Reading edition
Forms like fur-booted, blackeyed, etc., do not, of course, belong here. They are derived, with the suffix ed, from compounds or groups like fur-boot, black eye, eagle eye, cone-shape, etc., or formed by analogy to such derivatives. Some, indeed, are true compounds, but then the second element is an adjective and not a past participle. In that case they should be ranged under the compound formed from two adjectives.
