Tiny discussion of this word btw:
http://mail.lojban.org/lists/lojban-list/msg15745.html

pe'i "hyperbola" should be expressed with a fu'ivla. See how to express it
with a lujvo, you have to throw in gismu whose only purpose is to evoke
the desired meaning, whose places don't participate in the final place
structure.

ju'osai Even if "hyperbola" is expressed as a lujvo, with veljvo the
Lojban equivalent of "beyond parabola", farlu is more suitable than
selrer.
