Questions & Answers about Sistematik testler yapıldıkça mekanizmanın güvenilirliği de artıyordu.

What does the suffix -dıkça in yapıldıkça mean, and how is yapıldıkça formed from the verb yapmak?

-dıkça is a conjunctional suffix meaning “as…,” “whenever…,” or “the more…, the more….”
Breakdown of yapıldıkça:
• yap- (do)
• -ıl- (passive marker: “to be done”)
• -dık (past participle: “having been done”)
• -ça (as/whenever)
Altogether, yapıldıkça literally means “as it was done,” here “as systematic tests were performed.”

Why is the verb artıyordu in the past-continuous form -yordu, and how does it differ from the simple past arttı?

The suffix -yordu expresses an ongoing or habitual action in the past.
• artıyordu = “was increasing” (gradually/continuously)
• arttı = “increased” (simple past, a single completed event)

What is the function of de in mekanizmanın güvenilirliği de artıyordu, and why is it written separately?

de here is a clitic meaning “also/too.” It attaches to mekanizmanın güvenilirliği to show that its reliability was increasing too (in addition to something else). According to Turkish orthography, this de is written as a separate word, without an apostrophe.

Why is mekanizmanın in the genitive case and güvenilirliği in the possessive form, instead of simply saying mekanizma güvenilirliği?

Turkish uses a genitive-possessive construction for “X’s Y”:

1. Possessor takes the genitive suffix -nın → mekanizmanın (mekanizma + -nın)
2. Possessed noun takes the 3rd person singular possessive suffix -i → güvenilirliği (güvenilirlik + -i)
   Thus mekanizmanın güvenilirliği = “the mechanism’s reliability.”

How do you form the passive voice in Turkish, and why is yapılmak used instead of yapmak in this sentence?

To form the passive, insert -ıl- / -il- / -ul- / -ül- (according to vowel harmony) after the verb root. Here:
• yap- (root “to do”)
• -ıl- (passive) → yapıl- (“to be done”)
Since the actor isn’t specified, sistematik testler yapıldıkça means “as systematic tests were done.”

Why doesn’t the adjective sistematik take a plural suffix when modifying testler?

In Turkish, adjectives never change for number. Only the noun gets the plural suffix -ler/-lar. So sistematik testler correctly means “systematic tests.”

Can you break down the word güvenilirliği and explain each component?

Sure:
• güvenilir = reliable
• -lik = noun-forming suffix → reliability
• -i = 3rd person singular possessive suffix → its reliability
Combined: güvenilir + lik + i = güvenilirliği (“its reliability”).
