P. S.
I mixed up sematics of modal connective in M2, because places in connectives work in reverse:
7.1) le spati cu banro ri'a le nu do djacu dunda fi le spati
7.5) do djacu dunda fi le spati seri'a le nu ri banro
7.6) le nu do djacu dunda fi le spati cu rinka le nu le spati cu banro
7.7) le spati cu banro .iri'abo do djacu dunda fi le spati
All sentences under this interpretation have same predicate structure:
P
1 :x
1 grows/expands [an increasing development] to size/into form {zo'e} from {zo'e}.
P
2: {nu} P
3 (event/state) effects/physically causes effect {nu} P
1 (event/state) under conditions {zo'e}.
P
3: y
1 [donor] (water-type of) gives/donates gift/present {zo'e} to recipient/beneficiary y
3 [without payment/exchange].
