But it MARKS it, which will draw focus.  And if it is marked as new 
information in particular, then I cannot see any reason for marking it 
UNLESS it is key.  Now it is possible to use bi'u/nai multiply and thus 
have multiple foci, which may not be a natlang sort of thing.

Can you come up with an example (in English if necessary) where the focus 
is NOT new information, and something else is new information, and you mark 
the latter vi'a special marker/grammar/emphasis, and not the former?

Be that as it may, I find in looking at ancient postings that this came up 
once before, from you, and Cowan opined that ba'e was the focus 
marker.  Much earlier, back in 1991, we apparently said that focus was 
conveyed primarily by position, with primary focus on the beginning of the 
sentence.

The reason for doing that is, I suspect, that in English we use focus as 
part of making that distinction.

I believe (and I'd welcome being corrected if wrong) that Russian and other 
languages that do not have definite/indefinite articles indeed usually use 
ONLY focus to make the distinction.

Or perhaps natural language is quite illogical, and logic is an attempt to 
impose an order on it that really doesn't apply, a model that is at best 
only approximate.

I don't understand this statement.  If you don't know what the focus is, 
then how can you even refer to it?

"if".

"That's the way JCB did it". For more details, I defer to pc.
