This doesn't seem to have *any relation to what you are asking about wwh, but, I found this in *my searches. There is just such a word in Greek, and it means 'line'. I found it while searching, in a page on Greek meter, which by itself makes interesting reading. The meter pattern for a distich is called 'hemiepes'. Bingley, come in...
Am posting the link if you are interested; scroll down till you find a paragraph titled, 'elegy and the five of nothing pentameter'. It is described there.
