Causing Outcomes (-masına sebep olmak)
In English, we often say "A causes B to happen." In Turkish, this is framed as "A leads to the happening of B." We express the outcome as a factive clause (a verbal noun) and link it to a verb of causation using the dative case.
To build this structure:
- Turn the result verb into a verbal noun using the suffix
-mA/-mE. - Add a possessive suffix to show who or what is performing the resulting action (e.g.,
-sI/-sifor "its" or "their"). - Add the dative case suffix (
-a/-e). Because you are attaching it after a third-person possessive, use the buffer lettern(-mAsIna/-mEsine). - Complete the thought with a causative verb like sebep olmak (to cause) or yol açmak (to lead to).
Notice how ölmek (to die) becomes ölmesine (to their dying) to link with yol açar.
| Inhaling exhaust gas in the city causes people to die early. | Şehirde egzoz gazı solumak, insanların erken ölmesine yol açar. |
Causes as Factive Clauses
The "cause" of an event can be a simple noun or an infinitive. However, often the cause itself is also a factive clause (e.g., "The factories' using of chemicals").
When both the cause and the result are actions, you will see the -mAsI verbal noun structure used twice: once for the cause (the subject) and once in the dative case for the outcome.
| Factories using toxic chemicals causes the fish to die. | Fabrikaların toksik kimyasallar kullanması, balıkların ölmesine sebep olur. |
Health and Environmental Impacts
This structure is highly useful when discussing complex cause-and-effect relationships, such as how pollution affects health.
| His inhaling dirty air led to lung diseases increasing. | Kirli havayı soluması, akciğer hastalıklarının artmasına yol açtı. |
| The water being dirty causes infections to start in children. | Suların pis olması, çocuklarda enfeksiyonların başlamasına sebep olur. |
| The weather suddenly getting cold caused his asthma to worsen. | Havanın aniden soğuması, astımının kötüleşmesine sebep oldu. |
Another helpful verb for discussing outcomes is tetiklemek (to trigger). Unlike sebep olmak and yol açmak, which require the dative case, tetiklemek takes a direct object. Therefore, the preceding word will take the accusative case (-i / -ı / -u / -ü).
| This toxic smoke triggers the children's cough. | Bu toksik duman, çocukların öksürüğünü tetikler. |
