neh-PLEZ-lee-ah
I think the emphasis is on the 'plez' part, it could be on the 'lee' as well.
it could also be: neh-PLESS-lee-ah
that double 's' is just to highlight the softness, don't extend the sound too much
EDIT: Also, is everyone happy with my meger lyrics? I kind of just wrote them down as my muse spat them out and did a little fine-tuning.
EDIT2: Also also, if you're going to start music'ing something up, I had a feeling that the second and fifth lines should be very loud and boistrous, like it was a drinking song, with the first and fourth lines the softest, but still very angry/tough/manly. (lyrics edited with line numbering)
