i / ı
Dotted I and Dotless I
Turkish has two distinct 'i' letters: i (dotted) and ı (dotless). They represent different sounds and are never interchangeable.
How It Works
In Turkish, the presence or absence of a dot changes the letter entirely. This is one of the most important features of the Turkish Alphabet.
1. The Dotted i (İ, i)
This letter sounds like the 'ee' in 'see' (IPA: /i/).
Lowercase: i
Uppercase: İ (Note: The dot stays!)
2. The Dotless ı (I, ı)
This letter has no direct English equivalent. It is a 'back' vowel, sounding similar to the 'e' in 'roses' or the 'u' in 'stadium' (IPA: /ɯ/).
Lowercase: ı
Uppercase: I
3. Why it matters: Four-Way Vowel Harmony
These two letters are part of the Four-Way Vowel Harmony system. Suffixes like the Accusative Case or the Past Tense choose between four vowels (ı, i, u, ü) based on the last vowel of the word root:
- Use ı if the last vowel is a or ı (e.g., kapı -> kapıyı).
- Use i if the last vowel is e or i (e.g., kedi -> kediyi).
- Use u if the last vowel is o or u (e.g., okul -> okulu).
- Use ü if the last vowel is ö or ü (e.g., göl -> gölü).
Note: In examples like kediyi, we use the Buffer Consonant -y- because Turkish does not usually allow two vowels to sit next to each other when adding a suffix.
Examples (4)
- İstanbul'da üç gün kaldık.
We stayed in Istanbul for three days.
Word by Word: Istanbul-in three day we-stayed.
Notice the capital 'İ' with a dot in 'İstanbul'. In Turkish, the dot is never dropped when capitalizing 'i'.
- Odanın ışığı çok parlak.
The light of the room is very bright.
Word by Word: Room-of light-its very bright.
The word 'ışık' (light) uses the dotless 'ı'. The suffix '-ı' also follows vowel harmony.
- Kır ve kir farklı kelimelerdir.
Countryside and dirt are different words.
Word by Word: Countryside and dirt different words-are.
This shows how one dot changes the meaning: 'kır' (dotless) means countryside, while 'kir' (dotted) means dirt.
- Ilık bir çay içtim.
I drank a lukewarm tea.
Word by Word: Lukewarm a tea I-drank.
The word 'ılık' starts with a capital dotless 'I'. If it were 'İlik', it would mean 'bone marrow'.
Common Mistakes
Capitalizing 'i' as 'I' (English style).
IstanbulİstanbulIn Turkish, 'I' is the capital of 'ı'. To write 'Istanbul' correctly, you must use the dotted 'İ'.
Using the wrong vowel in suffixes due to harmony errors.
BakdimBaktımSince 'bak-' has the back vowel 'a', the suffix must use the dotless 'ı' to match. 'Bakdim' is a harmony error.
