Vowels: Alpha to Omega

Greek was the first alphabet in history to represent vowels as full, independent letters. Understanding the seven vowel letters is your first step toward reading Greek fluently.

The Seven Vowel Letters

Modern Greek has five distinct vowel sounds but seven vowel letters. Some letters that were pronounced differently in Ancient Greek have merged to the same sound in Modern Greek.

Letter	Name	Uppercase	Lowercase	Modern Sound	Ancient Sound
Α α	Alpha	Α	α	"a" as in "father"	"a" as in "father"
Ε ε	Epsilon	Ε	ε	"e" as in "bed"	"e" as in "bed"
Η η	Eta	Η	η	"ee" as in "see"	"ay" as in "day"
Ι ι	Iota	Ι	ι	"ee" as in "see"	"ee" as in "see"
Ο ο	Omicron	Ο	ο	"o" as in "got"	short "o"
Υ υ	Upsilon	Υ	υ	"ee" as in "see"	"oo" as in "food" (or French "u")
Ω ω	Omega	Ω	ω	"o" as in "got"	long "o" as in "go"

Tip: In Modern Greek, η, ι, and υ all sound like "ee". This is called iotacism — a major sound shift that occurred over centuries.

The "ee" Sound (Iotacism)

One of the most notable features of Modern Greek is that three letters and several digraphs all produce the same "ee" sound:

Spelling	Example	Meaning
η	μήνας (meenas)	month
ι	πίτα (peeta)	pie/pita
υ	μύθος (meethos)	myth
ει	είναι (eeneh)	is/are
οι	οίκος (eekos)	house

This means spelling in Greek requires memorisation — you cannot always tell from the sound alone which "ee" spelling to use.

The Two "o" Sounds

Similarly, Omicron (ο) and Omega (ω) produce the same sound in Modern Greek:

Letter	Name	Meaning of Name
Ο ο	Omicron	"small o" (ο μικρόν)
Ω ω	Omega	"big o" (ω μέγα)

In Ancient Greek, Omicron was a short "o" and Omega was a long "o". Today the distinction is only in spelling.

Modern pronunciation:
  ο in πόλη (polee — "city")     sounds the same as
  ω in ώρα  (ora — "hour")
