Simultaneous cause and effect (-masıyla)

To link two events where one immediately triggers another, you can use the verbal noun combined with the instrumental case. This creates the meaning "with [event] happening..." or "upon [event] occurring...".

Forming "-masıyla / -mesiyle"

This structure requires two parts:

  • The subject of the action takes the Genitive case.
  • The verb takes the verbal noun suffix (-ma / -me), the 3rd person possessive suffix (-sı / -si), and the instrumental suffix (-yla / -yle).

Together, the verb ending becomes -masıyla or -mesiyle (following 2-way vowel harmony).

With the northeast wind starting, the sailor got cold.
Poyrazın başlamasıyla denizci üşüdü.
With the northeast wind filling the sails, the boat sped up.
Poyrazın yelkenleri şişirmesiyle tekne hızlandı.

Here are a few more instances of simultaneous cause and effect on the high seas. Notice how the genitive subject and -masıyla verb seamlessly connect a natural force or action directly to its outcome.

With the southwest wind picking up, the ropes stretched.
Lodosun çıkmasıyla halatlar gerildi.
With the storm intensifying, the boat capsized.
Fırtınanın şiddetlenmesiyle tekne alabora oldu.

Expressing Purpose with "diye"

To express "so that" or "in order to," use the word diye immediately after a verb expressing an intention. Usually, the verb before diye is conjugated in the optative mood (e.g., "let us do") or the imperative mood (e.g., "let him/it do").

The sailor turned the helm so that we wouldn't capsize.
Denizci alabora olmayalım diye dümeni çevirdi.

Making Deductions with "-mış olmalı"

When you observe an effect and want to express a strong assumption about its cause ("must have..."), combine the evidential past suffix (-mış / -miş / -muş / -müş) on your verb with olmalı (must be).

The storm must have ended; the crew went out to the deck.
Fırtına bitmiş olmalı, tayfa güverteye çıktı.
The captain must be tired; he left the helm to the crew.
Kaptan yorulmuş olmalı, dümeni tayfaya bıraktı.
