Another question in the theme of chosen names in The Left Hand of Darkness.
One of the main characters is named "Genly Ai". It is specifically noted in a couple passages in the book that "Ai" is pronounced like the English pronoun "I".
(One instance is towards the end of the story where Genly notes that Harth was unable to say his last name as "I" even in mindspeach).
Were it not for these couple of references I found it quite vague to know how to pronounce "Ai". Also it just seems a strikingly short, unusual choice of a name. So my question is: does "Ai" have any significance or meaning?
