First mooted on Lojban list:
So I think "experience of having legs" is NOT "li'i ce'u se tuple" but
rather "li'i le se NO'AU se tuple", where NO'AU = next outer phrase
(regardless of whether it is a bridi) = a sibling of NO'A.
--And
(sorry, I can't resist thinking that no'au is something like a strong form of ka'enai or .e'enai... zo'o)
