"With me or with Duo."

Translation: Benimle veya Duo ile.

[kensax]

Why is the suffix form not possible with Duo?

[Selcen_Ozturk]

Duo'yla is possible

[ChickenRunner02]

Why is there a 'y'?

[Laura847169]

because Duo ends with a vowel :)

[R_Andersson]

Yes, just as Laura said, it is a vowel buffer that is used when the noun ends in a vowel. It is also used with all the other cases.

[evelyn-miriam]

Hm, I forgot that. I thought the buffer y always devides two vowels. But for the buffer y after cases one vovel at the end of the case is enough, correct?

[KianSwami]

Is it wrong if i say benimle yoksa duo ile ?

[AlexinNotTurkey]

You would have to use the question particles in this case.

[FailingAgain]

How come in some cases -li (peynirli) is used whilst in other cases -le is used (benimle). Terribly sorry, I imagine it's a really simple answer....

[Hendshaheen2014]

They are two different grammers
1) "la/le" means with/and
2) li/lı/lü/lu is sort of like the "y" we add in English to transform a noun into an adjective
Peynir means cheese
Peynirli means cheesy
Peynirle with cheese
To illustrate more
Sütle pasta yerim (here you eat cake and drink milk with it - cake and glass of milk)
Sütlü pasta yerim (you eat milky cake / cake with milk inside it/ cake made with milk)
I hope this is clear in any way

[evelyn-miriam]

Oh, that´s a very helpful explaination. Thank you.

[anni158929]

why is it not 'benimle' and 'Duoylu' is it because names have 'ile' instead off the suffix?

[DuoLiNxo]

The instrumental case takes the 2-way vowel harmony:

(a, ı, o, u -> a) and (e, i, ö, ü -> e)

You can't have 'Duoylu'. It is either -(y)la or -(y)le. Following the rule you have 'Duoyla'.

---

Do not confuse instrumental case with the “with” or “without” whereas the suffixes are -lI and -sIz, which follow the 4-way vowel harmony.
