About this unit
Two more teams spell the i sound, plus a rare third. Read them easily, and learn each word’s spelling by sight.
- ΕΙει
ee, as in “see”κλειδί · keyi
Same i sound as ι, η and υ.
- ΟΙοιee, as in “see”οικονομία · economy
i
Same i sound; read the team together.
- ΥΙυιee, as in “see”υιός · son (formal)
i
A rarer i spelling, for recognition.
| Spelling | Example |
|---|---|
| ι | μάτι |
| η | ημέρα |
| υ | τυρί |
| ει | είμαι |
| οι | οικονομία |
| υι | υιός |
All six sound the same, so listening alone cannot tell you the spelling.

Ι, η, υ, ει, οι and rarer υι are spelling alternatives for i. In είμαι the tonos goes on the second letter of ει. Read the printed word and learn its spelling; sound alone cannot choose the letters.

son (formal)Use a Greek keyboard
Use the Greek layout or the course tiles. On a common Greek keyboard the ; key is a dead key for tonos: press it, then the vowel. Final ς has its own key. Keep the accent in ordinary lowercase words; normalise Unicode rather than removing tonos.
