jan Lope o, toki!
Congratulations on your grammar! You have just been quoted from it on Facebook, and so I had the opportunity to take a look at it. I have an urging question: in "Several pi-Phrases for one Compound Noun" you leave out the comma in "kulupu pi kalama musi→,← pi ma Inli li
pona." You seem to do this because "pi phrases are not nested," so leaving out the comma doesn't do any harm. But where do you have this information from? I can't find hints in either jan Pije's pages nor in jan Sonja's book.
But, in jan Sonja's book I can find grouped li-phrases that have commas, as in "jan Isa li tawa lili, li kama anpa, li toki e ni tawa sewi: ..." I would expect the same thing to be possible with grouped pi-phrases. Since I don't see why nesting is not allowed, I would read multiple pi-phrases without commas as nested.
