How to paint

[zeno@deltanet.com)]

Howdy all,

I have the lists from the following sites:
   http://www.lojban.org/files/wordlists/gismu
   http://www.lojban.org/files/wordlists/cmavo
   http://www.lojban.org/files/wordlists/lujvo-list

I have learned what most of the fields in the records are, but I have
some questions, and I wonder if anyone can help me.  I have the
following definitions from the lujvo-list and gismu files:

   cintyfaigau:cinta+fatri+gasnu:to paint something:$gasnu1 $fatri1
   $=cinta1 $fatri2

   cinta              paint                                     
   x1 [material] is a paint of pigment/active substance x2, in a base
   of x3                         a    6    (cf. pixra, skari)

   fatri         fai  distribute                                
   x1 is distributed/allotted/allocated/shared among x2 with
   shares/portions x3; (x2/x3 fa'u)       8c  22    [also spread,
   shared out, apportioned; agentive distribution (= fairgau,
   fairzu'e)]; (cf. cmavo list fa'u, fendi, preja, katna, tcana)

   gasnu         gau  do                                        
   x1 [person/agent] is an agentive cause of event x2; 
   x1 does/brings about x2                      2e 142    (cf. cmavo
   list gau, gunka, zukte, rinka, fasnu for non-agentive events,
   jibri, kakne, pilno)

For cintyfaigau, I assume the sumti are not taken from gasnu, but are
the doohickeys listed with dollar signs after the definition, which
would make the sumti x1 from gasnu x1, x2 from fatri x1, x3 from cinta
x1, and x4 from fatri x2.  Can anyone tell me what the equals sign
means on x3 ($=cinta1)?

If I am right, then I would have:
   x1 from gasnu person/agent
   x2 from fatri as what is spread (paint?)
          (but since x3 seems to also be paint, perhaps this
           is the thing painted if one is painting a picture of
           something?)
   x3 from cinta as material (paint?)
   x4 from fatri as what x3 is spread among (on?)

I paint the house = mi cintyfaigau fo la zdani
I paint the scenery = mi cintyfaigau la jvinu
I paint a picture = mi cintyfaigau fo la pixra

I don't know if the "la"s are supposed to be there when "fo" is used.
Obviously, I don't know what the heck I'm doing :-!  What am I doing?
