Listed as for deletion as there are no references and this term is nothing but an incorrect use of a slash to indicate alternation. Correctly it should be he/she, she/he. A case could be made for s'/he but it would be very weak.
Redirect edit
On 19 October 2006, the decision of Wikipedia:Articles for deletion/S/he was that S/he be redirected to the article Gender-neutral pronoun. Since then, the redirect has been removed twice, and the article restarted. Please do not unilaterally restore this article again.
If anyone wishes to discuss re-creating a separate article for "S/he", please discuss on Talk:Gender-neutral pronoun. Thanks. / edgarde 10:32, 4 May 2007 (UTC)
