Ancient Greek Pronounciation

On the very first contact with Ancient Greek, every student should probably feel the need to follow a rigorous system of pronounciation. With the first attempts of practicing conjugations, when trying to remember, writing from memory without consulting the textbook, such sequence as anthropos - anthropou - anthropo etc., he will probably ask himself, "How to write anthropon? Should I use omega or omicron? There must be both of them, but which one is first? Hmmm... if I knew how to pronounce the two letters so that they be distinct from each other phonetically, I would remember more easily how to employ them correctly...”

Various pronounciation systems are available

The German scholar J. Reuchlin (1445-1522) advocated the use of the pronounciation system of the Greek language of his time. The characteristics of this pronounciation system are mainly as follows.

η, ι, υ, οι, υι, ει, ῃ

are all pronounced alike:


αυ, ευ

are pronounced:

av, ev,


af, ef,


is pronounced:


The rough spirit is completely neglected.

This system could only prove itself legitimate for periods much later than the classical period. It contains inexplicable discrepancies between writing and pronounciation.

Erasmus of Rotterdam (1466-1536) brought forward arguments against such a pronounciation system, advocating a pronounciation system ad litteram, assigning each alphabet sign a distinct sound. Erasmus was against the modern Greek pronounciation system as applied to ancient Greek, based on the following principles:

- it is illogical to have several signs for the same sound without reasonable etimological motivation;

- texts engraved in stone by common people in ancient times rarely show mistakes that could be attributed to confusions related to pronounciation.

- there are grammar forms that are different from each other by signs which would be pronounced, according to the reuchlinian system, exactly the same way; the vocalic alternance with morphological role would have no sense if, for instance, ει/οι/ι would be pronounced identically, i.e., 'i'. Example: ἔλειπον = I was leaving; ἔλιπον = I left.

- the way some Greek words were transliterated into Latin is also supporting an ad litteram pronounciation system. (Ex: phoenix < φοίνιξ = red; aether < αἰθήρ = air).

- Greek grammarians showed that η compared with ε is as ω compared to ο, i.e., η = ε + ε; ω = ο + ο.

Other systems have been proposed in the meantime; see for example http://www.biblicalgreek.org/links/pronunciation.php and http://www.letsreadgreek.com/Resources/greekntaudio.htm

What do I choose?

The pronounciation system that I propose here is based on the following simple principles:

1. The phonetic system of modern Greek is employed to the extent that this does not cause important difficulties or confusions.

2. The main 'witness' to appeal when judging the extent of applying the modern Greek phonetics is the accentuation system of ancient Greek.

The way letters and combinations of letters are to be pronounced is described below. In order to understand why some features of modern Greek phonetics are maintained and some other are not, a parallel is made between the two generations of this language – ancient vs. modern.
