I've downloaded the gadget.html and am wondering what are the categories under which the words had been grouped:
e.g.
133001 banzu suffice
133001 batke button
133001 bridi predicate
133001 claxu without
133001 cliva leave
133001 crepu harvest
133001 cripu bridge
133001 curve pure
133001 dandu hang
133001 dinko nail
133001 dukse excess
133001 fenra crack
133001 fenso sew
133001 ganzu organize
133001 gletu copulate
133001 gunma jointly
133001 guska scrape
133001 ja    or
133001 jbini between
133001 je    and
133001 jganu angle
133001 jgena knot
133001 jimca branch
133001 jivbu weave
133001 jmaji gather
133001 jmina add
133001 jo    if	and only if
133001 joi   mixed with
133001 jorne joined
133001 ju    whether
133001 kansa with
133001 kanxe conjunction

These have something in common with the idea of "joining"/"separation", but what's with e.g. "banzu suffice", "claxu without",
"cliva leave", "crepu harvest", "curve pure"?
What have e.g. 

512211 forca fork
512211 jaspu passport
512211 nilce furniture
512211 pindi poor
512211 skami computer
512211 mansa satisfy, etc. etc.

in common???  ma ka'e sidju mi

mi'e la .aulun.
