It is possible that grammar may have to be passive before it becomes active, in which case it makes good sense to build up the foundations of passive grammar. Bulgarians, for instance, have an enormous reservoir of passive Russian grammar, due to the similarities between their two languages, but not that many of them have had occasion to acquire communicative competence in Russian. Passive grammar, then, may be a necessary step toward active use, but it by no means a sufficient one. We are talking about a potential tool, not a magic wand. Az iskam podarak.
Te iskaha kolata.
Nie iskahme tova. Toi iskashe vsichko. Vie iskahte mnogo. Vie vzehte kolata. Te nyamaha vreme.
