Cniglic (SHNEE-gleesh) is a subset of Lojban which I discovered roaming wild in Lojbanistan. I am now trying to tame it & structure it, for use both as an entryway to the full Lojban and as a useful language in its own right. It consists of approximately 93 words:
bu'o - BOO-ho - start emotion - continue emotion - end emotion dai - dye - marks empathetic use of preceding attitudinal; shows another's feelings fu'e - FOO-heh - begin explicit scope fu'o - FOO-ho - end explicit scope ge'e - GEH-heh - unspecified emotion pei - pay - emotion question
ba'a - BA-ha - I expect - I experience - I remember ca'e - SHA-heh - I define ja'o - ZHA-ho - I conclude ju'a - ZHOO-ha - I state - (default) elliptical/non-specific basis ka'u - KA-hoo - I know by cultural means (myth or custom) pe'i - PEH-hee - I opine (subjective claim) ru'a - ROO-ha - I postulate se'o - SEH-ho - I know by internal experience (dream, vision, or personal revelation) su'a - SOO-ha - I generalize - I particularize; discursive: abstractly - concretely ti'e - TEE-heh - I hear (hearsay) za'a - ZA-ha - I observe
ba'u - BA-hoo - exaggeration - accuracy - understatement da'i - DA-hee - supposing - in fact do'a - DO-ha - generously - parsimoniously je'u - ZHEH-hoo - truth - falsity ke'u - KEH-hoo - repeating - continuing la'a - LA-ha - probability - improbability li'a - LEE-ha - clearly - obscurely mu'a - MOO-ha - for example - omitting - end examples pa'e - PA-heh - justice - prejudice ra'u - RA-hoo - chiefly - equally - incidentally sa'e - SA-heh - precisely speaking - loosely speaking sa'u - SA-hoo - simply - elaborating ta'o - TA-ho - by the way - returning to main point to'u - TO-hoo - in brief - in detail va'i - VA-hee - in other words - in the same words zu'u - ZOO-hoo - on the one hand - on the other hand
A little more info:
The BPFK (baupla fuzykamni, language-plan responsible-committee) is working on a Lojban dictionary. Here's various relevant sections:
The classic work on Lojban is The Complete Lojban Language by (mostly) John Cowan. Chapter 13 is about attitudinals.
And as far as I know, that's it! There have been a lot of discussions here & there about the meaning of the various words, but I don't know of any other formal writing that goes into attitudinals in particular. As Cniglic develops more, I hope that someday we can put together a dictionary of Cniglic, with lots of examples & illustrations & everything.
