To express that a situation will continue under certain conditions—meaning "as long as" or "provided that"—Turkish uses the word sürece paired with a special verb form.
To build this structure, attach the suffix -dık / -dik (or its vowel harmony variants) to the verb stem, followed by a possessive suffix to indicate who is performing the action. Finally, add the word sürece.
Because possessive suffixes usually start with a vowel, the k in -dık softens to ğ. For a third-person subject ("as long as it does"), the ending becomes -dığı or -diği.
Changing the Subject
The subject of the condition is controlled entirely by the possessive suffix on the verb. For example, "as long as you look" uses the second-person singular suffix (-ın / -in), creating baktığın sürece.
Negative Conditions
To state that something holds true "as long as a subject does not do something", insert the negative suffix -ma or -me directly after the verb stem, before the -dık suffix.
States and Adjectives
When your condition describes a state or a quality rather than an action—such as being closed, open, or critical—use the helper verb olmak (to be). It takes the exact same suffixes, most frequently appearing as olduğu sürece (as long as it is).
