The deceased is probably what would be called today a classicist (the classical philologist of yesteryear). Here's a list of words (the first two of which are Latin, the others Greek):

calculus -- pebble
tussis -- cough
hoti -- for what, wherefore; that; for that, because
oun -- certainly, in fact; so then; therefore
de -- but

The poet also mentions enclitics which are small particles that attach themselves to words. (The meaning in Greek is leaning on, like Latin incline.) Sort of like English "n't" in can't. An example from Latin is -ne which marks a yes/no quesstion.

Greek has a bunch of particles, which are small words that change the meaning of a sentence or clause subtly. I have a book devoted entirely to them which is about 600 pages long.
