Re: [bpfk] pi PA [sumti]



Just for info, I used to discuss the related problem on the CLL:
http://groups.google.com/group/lojban/browse_thread/thread/e8b440f179edc867
At that time, I did not add an erratum to the CLL errata page, but it seems better to do it.

piPA [sumti]  =  lo piPA si'e be pa me [sumti]

http://www.lojban.org/tiki/BPFK+Section%3A+Numeric+selbri

cmavo: si'e (MOI)
Proposed Definition

Converts a number, lerfu-string or ME-converted sumti into a tanru-unit. The place structure in the case of a number is "x1 is/are a [number]th of x2". In general for any sumti the place structure is "x1 is a part/fraction of x2, quantified by [number/lerfu/sumti]".

Isn't there a contradiction between the proposed expansion for {pi PA [sumti]} and the definition of {si'e}?
Shouldn't the former be {pi PA [sumti] = lo me li pa fe'i PA me'u si'e be...}, or something like that?

The definitions are horribly worded, but "pi mu" is supposed to be one half, or five tenths, not one fifth, and "pi mu si'e" is like "xadba". 
  
Besides, isn't it weird that {pi ro ko'a} has a different meaning from {pa ko'a}?

"pi ro ko'a" ("the whole of ko'a") only really makes sense when ko'a is one (and if ko'a happen to be many I think "pi ro" forces a one group interpretation so that a whole can make sense. OTOH, "pa ko'a" ("one of ko'a") only really makes sense when ko'a are more than one, and it's weird if not meaningless when ko'a is one. I would say that when ko'a is one, "pa ko'a" forces a multiplication of ko'a into instances or such. 

A better definition for "pi PA ko'a" might be something like "lo pi PA si'e be ko'a noi pi ro ke'a pa mei"
