[lojban] What's the deal with me'ispe and bunspe?

[Jonathan Jones <eyeonus@gmail.com>]

Why is bunspe defined as sister-in-law and me'ispe is brother-in-law? That's completely backwards.

Specifically, brother-in-law (me'ispe) is defined as "x1 is the spouse of the sister of x2 under law/custom/etc. x3"

and sister-in-law (bunspe) is defined as "x1 is the spouse of the brother of x2 under law/custom/etc. x3"

What if the spouse of the sister is a woman? Or the spouse of the brother a man? What about the sister or brother of the spouse?

By the current definitions, a woman who is married to a woman with a sister is a brother-in-law, and a woman married to someone with a sister has no lujvo. It also doesn't work for the relationship between a sibling of one spouse and a sibling of the other spouse.

With the above in mind, I suggest the following definitions for the two:

me'ispe: "m1 is the sister-in-law of m2"
bunspe: "b1 is the brother-in-law of b2"
tubyspe: "t1 is the sibling-in-law of t2"

Where in each case the bond (m3/b3/t3) is "x1 is, or is a sibling of, s1, s1 is married to s2, x2 is, or is a sibling of, s2, x1=s1 and x2=s2 is not true."

The definition for m3/b3/t3 given above only accounts for members of the same generation. I don't think that the mothers of the married couple are sisters-in-law, for example, but I may be wrong on that.

In any case, with the suggested definitions:

woman-A is married to man-B. C is A's brother, D is B's sister, E is B's brother
