Many people stress the wrong syllable in "encephalitis" — they say "en-SEF-ah-ly-tis" instead of "en-sef-ah-LY-tis." The stress belongs on the "LY" part near the end, not on the "SEF" part near the beginning.

Japanese breaks into four syllables: jap-a-NEEZ. Encephalitis breaks into five syllables: en-ceph-a-LY-tis. Said together, it's: jap-a-NEEZ en-ceph-a-LY-tis.
