<p>In this study of the Navajo language Professor Robert W. Young tackled what strikes both the learner and the native speaker as an insurmountable obstacle--that Navajo appears to be a verb-centered language in which all the verbs are &quot;irregular.&quot; In <em>The Navajo Verb System</em> Professor Young reveals both its structure and its inflection as entirely &quot;regular&quot; and based on definite rules of order.</p><p>A leading authority on Navajo verb morphology Young brought over sixty years of experience to this study. This volume which Young called a handbook not only details the features of verb structure and inflection but also reflects the grammatical processes that generate a wealth of concrete lexical derivatives from a relatively small number of abstract verbal roots.</p><p>This volume together with Professor Young&#39;s earlier books is a basic reference invaluable to advanced students linguists and native speakers of Navajo.</p><p>&quot;This fine study presents great sweeps of Navajo verbal structure essentially at a glance. . . . The various sets of morphologically homologous verb themes are set out by Mode category and &#39;conjugation&#39; so that all the elements that go to make up individual forms can be seen at a glance.&quot;--Professor Kenneth Hale MIT</p>
