For the rhyming letters Beta-Zeta-Eta-Theta, the American pronunciation ( -ayta) is closer to Classical Greek and the British pronunciation ( -eeta) closer to Modern Greek.The table, especially the all-important Classical Greek pronunciation column, is incomplete I ran out of patience.(TOW rhyming with COW, TAW rhyming with LAW)
I've rearranged the alphabet to put sort-of rhyming letters together, but all letters are there. The Wikipedia page on Pronunciation of Ancient Greek in teaching has more details.įor sake of completeness, here's a (very incomplete) table showing the pronunciation in American English, British English, Ancient Greek, and Modern Greek.

( quantum physics ) : Some texts use Ψ (uppercase) for the actual wavefunction that appears in the time-dependent Schrödinger equation, and ψ ( =Ψe iEt/ħ) (lowercase) for the time-independent spatial wave function that may exist for stationary states (and which then appears in the time-independent Schrödinger equation), but this distinction is not always observed.
