Questions & Answers about Samimi bir gülüş her şeyi çözüyor.
How is gülüş formed from the verb gülmek?
The word gülüş is created by adding the manner suffix -üş to the verb root gül- (to smile or to laugh). This suffix turns a verb into a noun that describes the "way of doing" the action. Here, the "way of smiling" simply translates to the noun "a smile".
Why is the word order Samimi bir gülüş instead of Bir samimi gülüş?
Why is there an -i at the end of her şeyi?
her şey means "everything". In this sentence, it is the direct object receiving the action of the verb çözüyor (solves). Turkish always treats her şey as a specific, definite thing, so it must take the accusative case suffix -i when it is the object of the sentence.
Why does the sentence use the present continuous çözüyor (is solving) instead of the simple present tense (solves)?
The verb root is çöz- (to solve or untie). While English uses the simple present tense to say a smile "solves" everything, it is very common in spoken Turkish to use the present continuous tense (-ıyor / -üyor) to state general observations, facts, and habits.
