Toward some transformation rules.

Given, for the moment that the basic tp sentence has the form (ignoring conditions)
Subj li Verb (e DO) (PP)
we can reach a few familiar sentences by known transformations:
{o,mi,sina} li A => {o,mi,sina} A  (obligatory)
A li B, A li C => A li B li C
A li B e C, A li B e D => A li B e C e D

(this one is ambiguous, since it might be taken to mean that, if C is a DO followed by a PP, and D is another DO followed by another PP, both of the PP would be copied as well,  We may want this or we may not; at present it seems we do.)
What about PPs?  A li B PP1 A li B PP2 => ?  A li B PP1 PP2?  A li B PP1 en PP2? A li B PP1 li PP2?
A li B, C li B => A en C li B (and similar rules for NP in PP, including complements to Prep verbs)
 A li Mod e ni: A li B => A li Mod B  (???  because of the -- to us -- ambiguity of the modals, this often doesn't seem to work out right and the A li Mod B may just be a construction rule)
Name o o Sent/VP => Name o Sent/VP
A li Prep NP e DO => A li Prep e DO Prep NP  (but 'lon' seems to go over to 'tawa'?)  This may be reversible.


on the noun/verb level
AB, AC => A pi B en C
