Constructions -IB TUR-, -IB YUR-, -IB YOT-, -IB O'TIR-

The constructions "verb-IB TUR-", "verb-IB YUR-", "verb-IB YOT-", "verb-IB O'TIR-", i.e. the past gerund followed by the auxiliary verbs tur- (root meaning: 'to stand'), yur- (root meaning: 'to walk'), yot- (root meaning: 'to be lying') or o'tir- (root meaning: 'to seat'), express a durative meaning (persistence of an activity), with either continuative (progressive) meaning or (only for "verb-IB TUR-" and "verb-IB YUR-") habitual (iterative) meaning.

- Continuative meaning (the continuity of an action).
That differs from focal present (-YAP), focal past (-YOTGAN EDI), progressive present (-MOQDA), progressive past (-MOQDA EDI), and momentary present (-YOTIR), which express only the fact that the action is (currently) taking place.

My head kept aching for several days.

Og'zingni tiyib yur!
Keep your mouth shut!

Bu haqda ko'p gapirib o'tirmayman.
I will not speak about it any further.

- The use of the indirective past (-IB) on the auxiliary verb strengthens the construction's progressive meaning. The action is taking place uninterruptedly at present time, and can sometimes also results from a change of state which has been inferred and not directly witnessed.
This construction is often referred as the continuous present.

U do'stini kutib o'tiribdi.
She is waiting for her friend.

Shu gapni aytib o'tirishibdi-ya!
That is what they were saying all the time.

- With the negative form of the gerund (-MAY), the construction expresses the continuation of a non-activity:

Yozmay turibdi.
He still does not write.

Biz ko'rolmay yuribman.
We are still unable to see.

U so'zlamay o'tiribdi.
He continues not speaking.

Ichmasdan o'tirdilar.

- Iterative meaning (habitual, typical or usual action), especially with tur-:

Tez-tez kelib turing.
Keep coming regularly.

Uni ko'rib turaman.
I keep seeing him from time to time.

U maktabda borib turadi.
He goes to school.

Bo'lib turadi.
That can happen.

- With the negative form of the auxiliary verb, the construction expresses an action which was planned, which was to be done, and which finally has not been performed:

Kutib turmadi.
He did not wait. (as was expected)

Xat yozib o'tirmadi.
He has not written the letter. (as was expected)
