l´m norwegian and try to study by my own until class begins nov.10.

English is not my mother language, therefore l don´t understand the mening of  -ýyor, -iyor, -uyor, -üyor in  -i type suffixes.

V+(ýyor/iyor/uyor/üyor) = am/is/are v+ing (present continuous tense)

If verbs and with a consonant you simply add suffix taking the vowel harmony into consideration (but only for the first part, -yor doesn’t change):

Kaç-ý-yor = he is escaping

Gel-i-yor = he is coming

Kýr-ý-yor = he is breaking it

Sil-i-yor = he is erasing it

Dol-u-yor = it is getting full

Böl-ü-yor = he is dividing it

Dur-u-yor = he is standing (there)

Düþ-ü-yor = it is falling (down)

If verb ends with a vowel, you drop that vowel and add the suffix as shown above. (It’s not a correct explaination grammatically but it is easier for you to understand that way)

De-mek = to say (drop the last vowel –e-)

D-iyor = he is saying

Ara-mak = to search (drop the last vowel –a-)

Ar-ýyor = he is searching

Baþla-mak = to begin (drop the last vowel –a-)

Baþl-ýyor = it is beginning

Sometimes 2 different verbs have the same form because of this drop:

Kur-mak = to set up

Kur-uyor = he is setting (it) up

Kuru-mak = to get dry (drop the last vowel –u-)

Kur-uyor = it is getting dry (it is shown as kuru-yor grammatically now you should have an idea why I said it is grammatically incorrect)

we are using them for  present continous tense

-ýyor,-iyor,-uyor,-üyor is like -ing

geliyoru(m)-(i´m) coming 

subject is hide we can find subject with a question

question: kim geliyor?   answer: (ben) geliyoru(m)

you are coming= geliyorsun

who is coming= kim geliyor  answer: (sen) geliyorsu(n)

ben geliyorum  :i´m coming

sen geliyorsun  :you are coming

o geliyor          :he/she/it is coming

onlar geliyorlar :they are coming
