Orthography

The writing system used by Modern Greek is an alphabet with 24 letters.

The letter sigma is written as σ in the middle of words and as ς at the end of words.

Diagraphs

There is a set of letter combinations, known as digraphs which are used to represent sounds other than what their constituent letters usually would.

Sometimes, the letter combinations αι, ει, οι, υι, αυ, ευ, ηυ, ου are not meant to be treated as digraphs and their letters are supposed to be pronounced separately. This is indicated by placing a diaeresis (¨) on the second letter. If the stress falls on the first letter of such a combination, then the acute accent is written on it and the diaeresis (¨) is omitted (e.g. “τσάι” and not “τσάϊ”).

Accent Marks

The acute accent ´ is used to mark accented syllables in polysyllabic words and is placed on the vowel of said syllables. If the vowel is an uppercase letter, then the accent is placed up and to the left of it. If the letter is lowercase, then the accent is placed on top of it. In digraphs, the second letter takes the accent.

The acute accent can also appear in monosyllabic words to distinguish between words which would otherwise be written in the same way.

The diaeresis ¨ is used to indicate that two consecutive letters should not be treated as a digraph. It is placed on the second letter.

Phonology

Vowels

Modern Greek has five vowel phonemes.

Modern Greek Vowel Phonemes
FrontCentralBack
Close/i/ η, ι, υ, ει, οι, υι/u/ ου
Mid/e/ ε, αι/o/ ο, ω
Open/a/ α

The vowel phonemes are actualized by the following phones:

There is no distinction between long and short vowels.

The phoneme /u/ is actualized as the non-syllabic consonant allophone [w] when simultaneously unstressed and preceded by a vowel.

The phoneme /i/ also has a few consonantal allophones which occur when it is unstressed.

Info: Phonetic Changes before /e/ and /i/

The following phonemes change their actualization when followed by the Vowels /e/ and /i/:

  • /k/ is actualized as [c];
  • /g/ is actualized as [ɟ];
  • /x/ is actualized as [ç];
  • /ɣ/ is actualized as [ʝ].

This is true both within the bounds of individual words as well as across word boundaries.

[z]

The phoneme /s/ turns into /z/ when followed by a voiced phoneme (/v/, /ɣ/, /ʝ/, /) or one of /m/, /ɾ/ and /n/.

This is true both within the bounds of individual words as well as across word boundaries.

[mb], [n t] [nd], [n k] [ŋg]

Across word boundaries, the phoneme combinations [n p], [n t] and [n k] change to [nd], [n k] and [ŋg[, respectively.

Accent

Similarly to English, Modern Greek has a stress accent system in which every word has a syllable pronounced slightly louder and longer than the others. This syllable is marked by an acute accent.

Important: The Antepenultimate Rule

The stress of a word can only be in one of three possible positions:

  • oxytone - on the ultima (last syllable);
  • paroxytone - on the penult (second-to-last syllable);
  • proparoxytone - on the antepenult (third-to-last syllable).

This rule is never broken. It is so strong that it can force the stress to move in inflected forms of the same word, lest it is broken.

Info: Derived Stress

In certain situations, a single word may have two accented syllables:

This secondary stress is also marked by an acute accent.
