Ch. 2 : Vowel Harmony
The Eight Vowels of Turkish

There are eight vowels in Turkish which are divided into two groups as follows:
The A‑UnDotted Vowels
A I O U
The E‑Dotted Vowels
E İ Ö Ü
The vowels A and E
Forming the Plural
Either the Plural Suffix
‑ler or
‑lar is chosen to mirror the final vowel of its noun.
All other suffixes will follow these Vowel Harmony rules. To form the plural we have a choice to add either
‑lar or
‑ler to the word:
Plural of the A‑UnDotted Vowel Group

Add
‑lar to words whose final vowel is any of the
A‑UnDotted Vowels
balta final vowel
‑a axe
baltalar [balta‑lar]
axes
kapı final vowel
‑ı door
kapılar [kapı‑lar]
doors
palto final vowel
‑o overcoat
paltolar [palto‑lar]
overcoats
boncuk final vowel
‑u bead
boncuklar [boncuk‑lar]
beads
The vowels in these Turkish words are all of the
A‑UnDotted Group so the added Plural suffix
‑lar must also contain an
A‑UnDotted Vowel.
Plural of the E‑Dotted Vowel Group

Add
‑ler to words whose final vowel is one of the
E‑Dotted Vowels
ev final vowel
‑e house
evler [ev‑ler]
houses
kedi final vowel
‑i cat
kediler [kedi‑ler]
cats
göz final vowel
‑ö eye
gözler [göz‑ler]
eyes
ödül final vowel
‑ü present (gift)
ödüller [ödül‑ler]
presents
The vowels in these Turkish words are all of the
E‑Dotted Group so the added Plural suffix
‑ler must also contain an
E‑Dotted Vowel.
This echoing of the final vowel by the suffix is called
Vowel Harmony.
Some Exceptions In Formation of Words

There are a very few exceptions to this rule where the suffix does not vowel harmonize:
saat hour, clock
saatler hours, clocks
harf letter (of alphabet)
harfler letters
To form the word
rol rôle in Turkish the suffix
‑ler is added to form its plural
roller rôles. This is contrary to the general rule. Normally
‑lar would be added to
rol, as it contains the UnDotted Vowel
O.
Words like
rol also constitute exceptions when other suffixes are attached :
Bu rolü almak istiyorum
[rol‑ü NOT rol‑u]
I want to take (on) the this rôle.
Bu rolden çok bıktım
[rol‑den NOT rol‑dan]
I am really fed up with this rôle.
["‑den bıkmak" "to get fed up with"]
Bu rolde bir sürü aksaklık var
[rol‑de NOT rol‑da]
There is something wrong in this rôle.
Bu role hiç alışamadım
[rol‑e NOT rol‑a]
I could not get used to this rôle at all.
["‑e alışmak" "to get used to"]
Some Other Exceptions
Vaat Promise
Vaatler Promises
Vaadi Promise (obj.)
Vaadin of the promise
Vaade to the promise
Vaatten from the promise
Kalp Heart
Kalpler Hearts
Kalbi Heart (obj.)
Kalbin of the heart
Kalbe to the heart
Kalpten from the heart
Harf Letter (alpha.)
Harfler Letters
Harfi Letter (obj.)
Harfin of the letter
Harfe to the letter
Harften from the letter
There are imports from Arabic and other foreign languages which exhibit this irregularity.
Vowel Harmony of Suffixes

Words with their last vowel in the
A‑UnDotted Group take
‑lar as their plural. This rule applies for all suffixes which contain
‑a‑
Those words with an
E‑Dotted Group Vowel take
‑ler as their plural. This rule applies for all suffixes which contain
‑e‑
The common and important words in constant use
in, on, at, from, to, with, etc.
are suffixes in Turkish and are affixed to the word they modify.
The Principle of Vowel Harmony must be taken into account.
The Static Position (Locative) Suffix ‑da/‑de or ‑ta/‑te ‑in, on, at

For words ending in an
Unvoiced Consonant [p ç t k f h s ş], when adding a suffix beginning with a consonant then the suffix consonant
"‑d" changes to its Unvoiced Form
"‑t". See Ch. 3 Consonant Mutation
This suffix shows concrete place (static location):
Odadayım.
[oda‑da‑yım]
I am in the room.
Ali bey, evdeymiş.
[ev‑de‑ymiş]
Ali bey is at home.
kedide
[kedi‑de]
on the cat
kedilerde
[kedi‑ler‑de]
on the cats
girişte
[giriş‑te]
in/at the entrance
girişlerde
[giriş‑ler‑de]
in/at the entrances
evde
[ev‑de]
at the house, at home
evlerde
[ev‑ler‑de]
at the houses
köprüde
[köprü‑de]
on the bridge
köprülerde
[köprü‑ler‑de]
on the bridges
adamda
[adam‑da]
on the man
adamlarda
[adam‑lar‑da]
on the men
kapıda
[kapı‑da]
at the door
kapılarda
[kapı‑lar‑da]
at/by the doors
çıkışta
[çıkış‑ta]
in/at the exit
çıkışlarda
[çıkış‑lar‑da]
in/at the exits
odada
[oda‑da]
in the room
odalarda
[oda‑lar‑da]
in the rooms
Two suffixes have been used;
‑ler and
‑de or
‑lar and
‑da.
They are tagged together to make a single word in Turkish.
The suffix ‑dan/‑den or ‑tan/‑ten from, by, via, through

For words ending in an
Unvoiced Consonant [p ç t k f h s ş], when adding a suffix beginning with a consonant then the suffix consonant
"‑d" changes to its Unvoiced Form
"‑t". See Ch. 3 Consonant Mutation
This is the Motion Away suffix:
kediden
[kedi‑den]
from the cat
kedilerden
[kediler‑den]
from the cats
girişten
[giriş‑ten]
from/via the entrance
girişlerden
[giriş‑ler‑den]
from/via the entrances
evden
[ev‑den]
from home
evlerden
[evler‑den]
from the houses
köprüden
[köprü‑den]
from the bridge
köprülerden
[köprüler‑den]
from the bridges
adamdan
[adam‑dan]
from the man
adamlardan
[adamlar‑dan]
from the men
kapıdan
[kapı‑dan]
from the door
kapılardan
[kapılar‑dan]
from the doors
odadan
[oda‑dan]

odalardan
[odalar‑dan]
from the rooms
çıkıştan
[çıkış‑tan]
from/via the exit
çıkışlardan
[çıkış‑lar‑dan]
from/via the exits
Two suffixes
‑ler and
‑den or
‑lar and
‑dan have been used and tagged together to make a single word in Turkish.
The suffix ‑(ya)/‑(y)e to, towards
If the root word ends in a vowel then the buffer letter ‑y‑ is used to separate the suffix ‑e or ‑a
This is the Motion Towards suffix:
adama
[adam‑a]
to the man
adamlara
[adamlar‑a]
to the men
kediye
[kedi‑ye]
to the cat
kedi cat ends in a vowel so "kedi‑y‑e" is used [kedi‑e] would be incorrect.
kedilere
[kediler‑e]
to the cats
eve
[ev‑e]
to home
evlere
[evler‑e]
to the houses
kapıya
[kapı‑ya]
to the door
kapı door ends in a vowel so "kapı‑y‑a" is used [kapı‑a] would be incorrect
kapılara
[kapılar‑a]
to the doors
Examples which show the buffer ‑y‑ inserted
köprüye
[köprü‑ye]
to the bridge
köprülere
[köprü‑ler‑e]
to the bridges
odaya
[oda‑ya]
to the room
odalara
[oda‑lar‑a]
to the rooms
The Buffer Letter
‑y‑ is used when the word ends in a vowel. Turkish does not like two vowels to be together.
The Vowels I, İ and U, Ü
The Front Produced (Dotted) Vowels are formed at the the front of the mouth
similar to the French Language.
The Back Produced (UnDotted) Vowels are produced nearer the throat as in English.
The Four Forms of the Suffix ‑I‑
There are two different forms of I (İ) and two different forms of U (Ü) in Turkish.
- The UnDotted Forms of I or U must follow the A‑UnDotted group A I O U
- The Dotted Forms of İ or Ü must follow the E‑Dotted group E İ Ö Ü
The Principle of Vowel Harmony states that a suffix containing the letter
a can have two forms either
a or
e.
The the suffix
‑den from which is used with the E‑Dotted vowels and
‑dan, which is used with the A‑UnDotted vowels.
Suffixes which contain a (generic) letter
‑i can have four forms. These are
‑i ‑ı ‑u ‑ü.
For example the suffix
‑im my.
Its own vowel, basically the
‑i‑ changes to any of
‑i ‑ı ‑u ‑ü to mirror the last vowel of the word to which it is suffixed.
Similarly all other suffixes with an internal
‑i‑ vowel will follow these Vowel Harmony Rules
ev
house
evim
[ev‑im]
my house
evlerim
[ev‑ler‑im]

Choosing the correct vowel i ı u ü

The suffix form
‑im my follows words whose last vowel is
‑e or
‑i:
Harmonizing with final E‑Dotted Group Vowel
‑e in the root word:
bilet
ticket
biletim
[bilet‑im]
my ticket
Harmonising with final Dotted
‑i in the root word:
diş
tooth
dişim
[diş‑im]
my tooth
dişlerim
[dişler‑im]
my teeth
The suffix
‑im must contain a dotted
‑i‑ as it follows a vowel from the
E‑Dotted Group. This is also true of the plural form
‑ler
The suffix
‑ım my follows words whose last vowel is
‑a or
‑ı
Harmonizing with final A‑UnDotted Group Vowel
‑a in the root word:
at
horse
atım
[at‑ım]
my horse
atlarım
[atlar‑ım]
my horses
Harmonizing with final UnDotted
‑ı in the root word:
kız
girl
kızım
[kız‑ım]
my girl
kızlarım
[kızlar‑ım]
my girls
The suffix
‑ım must contain an UnDotted
‑ı‑ as it follows a vowel from the
A‑dotted Group. This is also true of the plural form
‑lar
The suffix
‑üm my follows words whose last vowel is
‑ö or
‑ü
Harmonizing with final Dotted
‑ö in the root word:
göz
eye
gözüm
[göz‑üm]
my eye
gözlerim
[gözler‑im]
my eyes
Harmonizing with final Dotted
‑ü in the root word:
gül
rose
gülümv[gül‑üm]
my rose
güllerim
[güller‑im]
my roses
The plurals
gözlerim and
güllerim take the
‑im suffix (not the
‑üm suffix as in the singular) as they immediately follow the final vowel
‑e of the plural
‑ler
The suffix
‑um my follows words whose last vowel is
‑o or
‑u
Harmonizing with final UnDotted
‑o in the root word:
jeton
token, jeton
jetonum
[jeton‑um]
my token, my jeton
jetonlarım [jetonlar‑ım]
my tokens, my jetons
Harmonizing with final UnDotted
‑u in the root word:
oyun
game
oyunum
[oyun‑um]
my game
oyunlarım
[oyunlar‑ım]
my games
The plurals
jetonlarım and
oyunlarım take the
‑ım suffix (not the
‑um suffix as in the singular) as they immediately follow the final vowel
‑a of the plural
‑lar
The Complete Rules of Vowel Harmony
Final Vowel is followed by Suffix Vowel UnDotted A I O U are followed by
A Dotted E İ Ö Ü are followed by
E
UnDotted A or I are followed by
I
Dotted E or İ are followed by
İ
UnDotted O or U are followed by
U
Dotted Ö or Ü are followed by
Ü
Ch. 3 : Consonant Mutation
Consonant Mutation
Changes in Spelling to reflect Changes in Pronunciation In Turkish the spelling of the words is changed when the pronunciation changes.
Generally this does not happen in English. When the pronunciation changes the spelling does not usually change.
English spelling is often changed when the pronunciation is the same so that we can recognize the correct meaning.
A number of words show this:
"meet vs meat, feet vs feat, right vs write, main vs mane, sea vs see", and many more. If English were written phonetically, the word "does" would be spelt "duz".
Turkish however, being a phonetically written language will make changes in spelling due to pronunciation changes. This is for ease of speaking and is concerned with consonants which have voiced and unvoiced equivalents.
About Voicing of Consonants
A voiced consonant is one where the voice is used to produce the sound "(as Letter D)" and an unvoiced consonant is where the voice is silent and only air is expelled to produce the sound "(as Letter T)".
In Turkish when a word ends in a consonant it is usually the Un‑Voiced Form.
The word for
letter is
mektup, but
my letter is
mektubum. The terminal
‑p has changed to
‑b‑ when it appears between two vowels.
This is because it is easier to pronounce in its Voiced form
"b."
In Turkish the spelling must reflect this change for the rules of phonetics to operate.
Unvoiced and Voiced Equivalents

Unvoiced
p equivalent to Voiced
b
Unvoiced
ç equivalent to Voiced
c
Unvoiced
t equivalent to Voiced
d
Unvoiced
k equivalent to Voiced
ğ
Unvoiced
f no equivalent
Unvoiced
s no equivalent
Unvoiced
ş no equivalent
Unvoiced
h no equivalent
The letters
f s ş h do not have a voiced form, but they do affect the added suffix as they are considered as unvoiced consonants:
raf
shelf
raftan
[not "rafdan"]
from the shelf
nefis
delicious
nefistir
[not "nefisdir"]
it is (certainly) delicious
sabah
morning
sabahtan
[not "sabahdan"]
from morning
güneş
sun
güneşten
[not "güneşden"]
from the sun
Words ending in an unvoiced consonant change to the voiced equivalent when a vowel is added:
bilek
wrist
bileği
[bileğ‑i]
his wrist
kitap
book
kitaba
[kitab‑a]
to the book
kağıt
paper
kağıdın
[kağıd‑ın]
your paper
Examples of Changes

Words ending in unvoiced
‑K change to voiced
‑Ğ‑ when a suffixed vowel is added:
köpek
dog
köpeğim
[köpek + im]
my dog
bacak
leg
bacağın
[bacak + ım]
your leg
topuk
ankle
topuğu
[topuk + u]
his ankle
bilek
wrist
bileğimiz
[bilek + imiz]
our wrists
gözlük
spectacles
gözlüğünüz
[gözlük + ünüz]
your spectacles
durak
bus stop
durağa
[durak + a]
to the bus stop
görecek

I shall see
yaptık
we did
yaptığımız
[yaptık + ımız]
that which we did
bardak
glass (tumbler)
bardağı
[bardak + ı]
his glass
The consonant change from unvoiced
‑k to voiced
‑ğ‑ when adding suffixes is the most widespread mainly because so many Turkish words end in a terminal
‑k
A Special Case Exception (terminal ‑nk)

Examples where terminal
‑nk changes to
‑ng when adding a vowel.
If the word ends in
‑nk, the terminal
‑k changes directly to a unvoiced
‑g as it is totally impossible to utter the letter cluster
‑nğ plus an added vowel.
denk
bale, equation
dengim
[deng‑im]
my bale
ahenk
harmony, accord
ahengi
[aheng‑i]
its harmony
kepenk
shutter (on a shop front)
kepenginiz
[kepeng‑iniz]
your shutter
renk
color
rengimiz
[reng‑imiz]
our colour
Other Consonant Changes

Some of the other unvoiced consonants which change to their voiced form in similar fashion are as follows:
‑p changes to
‑b in front of suffixed vowels.
‑ç changes to
‑c in front of suffixed vowels.
‑t changes to
‑d in front of suffixed vowels, mainly in verb and tense suffixes.

Terminal Consonant Rules
Words cannot end with the voiced consonants b c d g.
Words must end in the equivalent
unvoiced forms
p ç t k in order to finish the pronunciation without continuity thus helping the listener to determine word breaks in conversation
