I&#x27;ve never liked this, but I have to admit that logically, a mismatch in number is no worse than the mismatch in gender we get by using &quot;he,&quot; which has the disadvantage of being annoying to many people. And I don&#x27;t think efforts to make up a new pronoun are likely to succeed. Singular &quot;they&quot; might well be the future.<p>But if I could have my pick I&#x27;d go with &quot;um.&quot;
