Both of them are very smillar. Sometimes I use one of them and than I think the other fits better and change it.

The main difference is that while in "birisi" it is more likely to be a person, in "biri" it can be also an object. While some people might use "birisi" for objects, I think I wouldnt.

My translation would be as follows:

birisi: a person, somebody
biri: one of them, someone

Both of them could be used for people. Birisi sounds more formal to me and biri more informal.

I think biri has a wider usage and in some cases birisi shouldnt be used at all. For instance:

Biri gitti biri kaldı.
One done, one to go.

Aptalın biri geldi.
Akıllının biri bunu yapmış.

I. yapsak: simple tense (timeless) conditional mood.1. yap-sa-k: verb stem-conditional mood-personal suffix
2. has not a time expression.
3. includes a wish and implies that I would like it to be done. It can mean "I wish we would do it" or "lets assume we do it".
gitsek: 1. lets assume we go 2.I wish we would go

II. yaparsak: simple present tense conditional mood
1. yap-ar-sa-k: verb stem-simple present tense-condition mood-personal suffix
2. It is in the simple present tense. The conditional mood could be used with other tenses. For instance: yapacaksak, yaptıysak, yapmışsak, yapıyorsak.
3. There is a clear cause-result relationship here which could be expressed as "if this than that". There must be a follow up.
gidersek: 1. if we go...

As nicely shown above by tabard, in some cases while the first one may be used, the second one should not. Here are a few more exapmles:

Yapsak mı?
Shall we do it?

Ne yapsak?
What should we do?

Nasıl yapsak?
How should we do it?

Ne yapsak boş.
No matter what we do, it's useless.

Gitsek de, kalsak da farketmiyor.
It doesn't matter whether we go or stay.

The difference between the two is most typical in the question form:

I. Ankara'ya gitsek mi?
Should ve go to Ankara?

II.Ankara'ya gidersek mi ...
If we go to Ankara or ...
This one needs a continuation. For instance like this:
Ankara'ya gidersek mi yoksa gitmezsek mi ...

I.Partiye gitmesek mi?
Maybe we shouldn't go to the party.

II.Partiye gitmezsek mi...
If we go to the party or...
This one needs a continuation.
Partiye gitmezsek mi yoksa gidersek mi daha çok eğleniriz?

When I wrote the sentences I didnt realise the -ince suffix in them. I was trying to include 'olmak' but accidentially -ince was also there. The ince suffix has the following forms:
–(y)ınca, –(y)ince, –(y)unca, –(y)ünce
The last vowel of the verb stem determines wich one we use out of these four. For instance if the last vowel is a or ı the suffix is -ınca.
Last vowel - suffix chart:
a,ı > –(y)ınca
e,i > –(y)ince
o,u > –(y)unca
ö,ü > –(y)ünce

Example:
infinitive: koşmak
verb stem: koş
koşunca > when running

The buffer y is added when the verb stem ends with a vowel. The reason, as you might know, is to prevent two vowels coming next to each other.
Example:
infinitive: okumak
verb stem: oku
okuyunca: when reading

The main usage of this suffix is expresing time like in the examples above. So mostly we would translate this suffix as 'when'.
With 'kadar' like in 'gidinceye kadar' it can mean 'until'.
Example:
Ben gelinceye kadar bekle. > Wait until I come.

We have a member with a smillar nickname. Maybe you send her a PM and ask her whether or not the e-mail was from her.

On these boards you may not talk on what religion tells us on this issue or what some religious people in Turkia think about sex.
People who can not keep religion as a private issue and would like religion to spread on everything are not welcome here.
A message has been deleted. No public discussion about this message or I will delete them as well. You can send a PM if you would like. Of course you can continue discussing the issue itself. Regards.

The instruction language is English at Metu while in İstanbul Unv. and Çukurova Unv. it isn't.
Metu has lots of foreign students and the number of foreign students is probaby a few times more than the total of Istanbul and Çukurova Unv. have. At metu there will be more tolerance to different lifestyles and untraditional ways of living. Inside the campus there is much more independence and flexibility and noone really cares for others so much. What I mean by flexibility is something you will only understand if you actually require the flexibility and freedom in your life.
Metu also can provide a good accommodation as it has many facilities.
I studied a few years at Metu and I can tell you that if you go to Metu you will never want to go to somewhere else. The other universities you mentioned are not bad but there is a clear difference in many ways.

Tozu dumana katmak: making something impressive, being so fast that you rise dust around.

Tozu dumanı yutmak: being down, being behind of other racers, to breathe the dust of those who are in front of you.

Either you bite the bullet or you bite the dust.

Merhaba Şefika,
welcome to Turkish Class Forums. I have checked many different web sites and I cannot confirm that the names mentioned in the original text are the correct ones. There can be some mistakes with the names. But obviously I just translate what is in the text so here is your translation:

"On the tablets* there is no information whether or not the Hittites had a medical education facility. The texts mention they were inviting physicians from Babylon or Egypt when the rulers were ill 14.59. Also, the nonexistence of the word 'doctor' in Hittite Language can be considered as another sign that they didn't have enough information and know-how on this issue.
The word LÚA.ZU (man who knows the water), which was used by Hittites as an equal for physician, is Sumerian 60.

Deities in the Hittite pantheon; the God of waters Ea, the Goddess of healing Kamrušepa, and Black Goddess DINGIR.GE* are both associated to health and cleanliness. Having common Gods and Goddesses for them indicates that health and cleanliness was somehow combined in Hittite thought 6.7."


* "tablets" can be replaced with "clay tablets" if it is unclear from previous texts what is mentioned here.
** As far as I could find dingir in sumerian means god and ge means female. I couldnt find the goddess dingir.ge but somewhere else
http://users.cwnet.com/millenia/FUgods.htm I found this:
"Dravidian >>Hindu Kali =the black goddess of birth and death." I think dingir.ge just means goddess and whoever wrote the original lines has missed the name of the goddess.

Link I checked for terminology:

Anybody could try them but our existing masters and native speakers.
Copy and paste them and add space or a dash wherever necessary.
