In Turkish, when a situation is already in motion or a task has just been completed, you can suggest doing an extra, related action using the suffix combination -mışken. This acts as an opportunistic converb, translating roughly to "while you're at it" or "since [X] has already happened."
To form it, add the perfective suffix -mIş (following 4-way vowel harmony) and the converb -ken (which remains invariable). Because -mIş always ends in the consonant ş, you will never need a buffer letter y. The resulting forms are simply -mışken, -mişken, -muşken, and -müşken.
Running Errands
You will frequently hear -mışken used to tack on extra chores when someone is already out and about. It perfectly captures the logic of "Since I've already gone outside, I might as well do this too."
Making the Most of a Situation
This structure works beautifully for larger projects, like fixing a car or doing home maintenance. If you have already gone through the trouble of opening a machine or taking it to a shop, you might as well take care of other parts while you are at it.
Emphasizing the Opportunity with "Hazır"
To strongly emphasize that a golden opportunity has presented itself, place the word hazır at the beginning of the clause. While hazır normally means "ready," in this context it means "now that" or "since the opportunity is sitting right here."
| since / now that (seizing the opportunity) | hazır |
Dealing with Troubles
Sometimes the situation is not a happy opportunity, but rather a hassle that dictates your next move.
If a place or an object has caused you trouble, you can use -mışken to decide your next step based on that pre-existing annoyance—for example, deciding to abandon a task entirely.
