Questions & Answers about Öğrenciler matematik testlerine tabi tutuluyor.

What does tabi tutulmak mean in this sentence?

The phrase tabi tutulmak literally means “to be subjected to” or “to undergo.” It comes from the adjective tabi (“subject to”) plus the passive form of tutmak (“to hold, to make someone do something”). So X, Y’ye tabi tutulmak = “X is subjected to Y.” In your example, öğrenciler matematik testlerine tabi tutuluyor means “students are being subjected to math tests.”

How is tutuluyor formed, and why is it passive?

tutuluyor is the passive present-continuous form of tutmak. Here’s the breakdown:
• tut- (root “hold/make someone do”)
• ‑ul- (passive suffix) → tutul- (“be held, be subjected”)
• ‑uyor (present-continuous) → tutuluyor (“is being subjected”)
Because we use the passive, there is no person/number ending on the verb.

What case and meaning does testlerine carry? Why so many suffixes?

testlerine is in the dative case (“to/into”), and it also carries plural and possessive markers. Break it down:
• test (root “test”)
• -ler (plural) → testler (“tests”)
• -in (3rd-person plural possessive) → testlerin (“their tests”)
• -e (dative) → testlerine (“to their tests”)
So in context it literally says “students are being subjected to their math tests.”

Could you say matematik testlere instead of matematik testlerine?

If you drop the possessive, testlere simply means “to tests.” In many contexts that’s fine—öğrenciler matematik testlere tabi tutuluyor would be understood as “students are being subjected to math tests” in general. Adding -lerine (“their tests”) emphasizes that these tests belong to or are assigned to the students.

Why is matematik not inflected at all? How can a noun modify another noun in Turkish?

Here matematik functions like an English attributive noun (“math”). In Turkish, many nouns—especially loanwords—can modify another noun without any suffix. You could also express “the tests of mathematics” by saying matematiğin testleri, using the genitive-possessive construction, but the simpler matematik testleri is very common.

Why is öğrenciler unmarked (no suffix)? How do we know it’s the subject?

In Turkish the nominative case (subject) has no suffix. Word order and context usually signal who is doing the action. Verbs in the 3rd person (active or passive) don’t change form for singular vs. plural, so you rely on the noun phrase öğrenciler (“students”) at the front to indicate the subject.

Why use the passive here? Who’s doing the subjecting?

The passive (tutuluyor) lets you focus on the students and omit or hide the agent (the school, teacher or exam board). If you wanted to name the agent, you could say:
Öğrenciler okul yönetimi tarafından matematik testlerine tabi tutuluyor.
= “Students are being subjected to math tests by the school administration.”

Is tabi tutulmak the same as maruz kalmak (“to be exposed to”)?

They overlap but aren’t always interchangeable.
• maruz kalmak often implies exposure—especially to something harmful or unwanted (e.g. “to exposure to violence,” “to criticism,” “to toxins”).
• tabi tutulmak is more neutral/formal, used for procedures, rules, tests, regulations, treatment, etc. (“to be subjected to a procedure,” “to be subjected to a law,” “to undergo a test”).
