Subjunctive _by_ in Polish

[Loren A. Billings]

Dear colleagues,

I am interested in the constituent order of the subjunctive particle _by_
in Polish, as in the following example:

     Bo by drukarza zabyto.

Here the constituent _by_ seems to be in second position.  I have found other
examples, however, in which _by_ seems to follow the verb:

     tan'czonoby (unfortunately only a single word)
     s'piewanoby (  "  )

Can anyone clarify?  Best,  --Loren Billings (billings at mailer.fsu.edu)
