Can an Aes Sedai bound to the three oaths use sarcasm?

Question

All Aes Sedai are bound by a ter'angreal called the Oath Rod and then sworn to obey the following Three Oaths:

1. To speak no word that is not true.

2. To make no weapon with which one man may kill another.

3. Never to use the One Power as a weapon except against Darkfriends or Shadowspawn, or in the last extreme defense of her life, the life of her Warder, or another Aes Sedai.

Does "speak no word that is not true" require one to follow this to the most literal sense of the phrase, or could you speak a false word so long as you know the recipient understands it to be sarcasm?

Can Aes Sedai bound to the Three Oaths use sarcasm?

Answer 1

Yes.

See this interview. In the words of Robert Jordan himself (emphasis added by Rand al'Thor):

the oath against lying does leave room for sarcasm. It is intent and result that matter. No sister can intentionally speak an untruth either with the intent of passing on false information or with the belief that false information might be passed on. Thus the careful slicing and dicing of words. But if someone were to hold up a piece of white cloth and ask whether it was black or white, someone who had sworn the Three Oaths would be capable of saying that it was black as a matter of sarcasm. But not if, for example, the person asking the question was blind and thus might well take the statement for truth rather than sarcasm.
