Greek 101

To have another language is to possess a second soul. ~Charlemagne

The accent, if written, is placed on the single vowel or the second vowel of the diphthong. If the diaeresis (two dots on top ΪΫϊϋ) is placed on the second, or the accent is on the first, it is not a diphthong. For example, ρολοϊ (clock, from ωρολογιον, whence French horloge) is pronounced roh-LOH-ee.
