‘Ayşe may have shown this photograph to Hatice.’
In some occurrences of the -mIş olacak combination, olacak can have one of the modal

This usage is rather rare.

A.-Turgut bana selam vermedi.
‘Turgut didn’t say hello to me.’
B.-Seni o kıyafette tanımamış olacak.
‘He won’t have recognized you in that outfit.’
(ii) Volitional modality (expectation) (21.4.4.2 (iv)):
(179) Akşama kadar bütün bu gazeteler paketlenmiş olacak.
‘All these newspapers are to be (lit. are to have been) parcelled up by this
evening.’
Compounds formed with -mIş olur present a hypothetical situation, such as one
dependent upon the fulfilment of a condition:
(180) [Daha geç bir saatte gitsek] sokaklar boşalmış olur.
‘[If we went later in the day] the streets would be less crowded.’ (lit. ‘would have
emptied’)
With olmalı an obligative reading is possible in addition to the assumptive one noted
above:
(181) 6.30’a kadar yola çıkmış olmalıyız.
‘We must be on the road (lit. must have set out) by 6.30.’
The optative forms olayım/olalım and the 3rd person imperative olsun(lar) can combine
with -mIş to express the suggestion or (in a noun clause, 24.2, 24.3) the wish that an
action be completed by a certain time:
(182) [Bu akşama kadar bu odayı bitirmiş olalım] istiyoruz.
‘We want [to have finished this room by this evening].’
21.5.1.1 The resultative usage of compound verb forms with -mIş
A further element of meaning that is present in some instances of compound forms with -
mIş is that the event is presented as happening as the result (intentional or not) of the
performance of some other act. This meaning is always present in the combination -mIş
oldu, which expresses, as a completed event, entry into the state of having done
something (a concept difficult to express in English, cf. 21.3.3):
(183) Dördüncü bölümün bitmesiyle kitabın yarısı yazılmış oldu.
‘With the completion of the fourth chapter, half of the book has been written.’
