question I can't parse into a Subject Line

 sorry.

 Watching 'The Discovery Channel' today, heard something about "in a Burundi
language" (apologies if I misspelledd anything in there)....when one person
talks to a person of higher status, the (lower-status) person deliberately
speaks ungramattically.

 are there other languages with that feature?  if so, or if not, how does
one distinguish between ungrammatical sentance and unusual (but grammatical)
?

 ie -
"tree fell man"

 now, is the sentance an SVO about a bonsai tree falling from a man's
grasp...or an OVS about a man falling out of a tree?  how does one
distinguish the two, when first encountering the language for the first
time? (ie, in a Relay).

 *curious*
