Markers
What if we were to "mark" each word with its function in the sentence?
Then we could say either of these:
KayS
seesV
the catO.
The catO
seesV KayS.
We'd always know which word was the subject and which one was the object. Then
we could use word order as a matter of convenience rather than as a means of
establishing who's who.
Well, that's exactly the approach that Korean takes.
