How it sounds

Av before a vowel or a voiced sound, af before a voiceless one and at the end of a word

αύριο (ávrio) comes out "avrio", αυτός (aftós) "aftos". One rule: after an a, υ adapts to the next sound

The character in a word

A lone character is hard to remember: memory holds on to meaning, and a letter has none. The word it stands in provides that anchor.

The character in the “letter pairs” group

Eleven pairs of letters read as one sound. Nothing can be read without them: Greek has no separate letters for the oo, b, d and g sounds at all. They are written with the pairs ου, μπ, ντ, γκ.

And come back to it the next day, not in an hour: a check a day or two later beats a check the same day. Nobody holds the whole alphabet — 24 letters — at once.
