query on poetic figure

[Arnold Zwicky]

i feel really stupid asking this, but at the moment i can't recall the name of the well-known poetic figure in which a word is split between two lines.  it's often done in songs, to get a rhyme or to set up a temporary ambiguity ("She got pinched in the As / Tor Bar", "Which only goes to show why I'm a broad / Shouldered guy"), but it can also be done to throw emphasis on the material at the end of the first line or the material at the beginning of the second, or for other reasons, as in the mini-poem i posted here:

http://arnoldzwicky.wordpress.com/2010/07/01/mini-poem/

where

  tetra
    metrical

and

  trocha
    icity

are both split, for, well, metrical reasons.

surprisingly hard to search for if you don't have a clue about the term.
