Zincir ölçer rublede kullanılmaz.

It can be analyzed as:

• kullan- = use
• -ıl- = passive
• -maz = negative aorist / negative general-present

So kullanılmaz means something like is not used or does not get used.

In this sentence, it is a general statement, not something happening only right now.

The ending -maz is the negative form of the aorist, which is often used in Turkish for:

• general truths
• habits
• rules
• things that are generally done or not done

So kullanılmaz means is not used in general.

If the speaker wanted to emphasize something happening right now, Turkish would normally use a different form.

Turkish often uses the passive when the important idea is the thing itself, not who does the action.

So instead of saying something like:

• People do not use a chain gauge ...

Turkish can naturally say:

• Zincir ölçer ... kullanılmaz.
• A chain gauge ... is not used.

This is very common in descriptions, instructions, formal writing, and general statements.

Because Turkish does not need a separate auxiliary verb here.

In English, you say is not used with the verb to be plus a past participle.
In Turkish, that whole idea is packed into one verb form:

• kullanılmaz

So the meanings of is, not, and used are expressed inside the Turkish verb itself.

Rublede is:

• ruble
  • -de

The suffix -de is the locative case, which usually means:

• in
• on
• at

So rublede means in/on/at the ruble, depending on context.

Grammatically, this is straightforward Turkish: a noun plus the locative ending.

That suffix changes form because of two common Turkish sound rules:

1. Vowel harmony

   • The last vowel of ruble is e, a front vowel.
   • So the suffix uses e: -de, not -da.

2. Consonant voicing

   • Because ruble ends in a vowel, the suffix begins with d, not t.

So:

• ruble + de = rublede

If the noun ended differently, you might see one of the other forms.

It is written as two words, but it functions as a single compound expression.

• zincir = chain
• ölçer = measurer / gauge / measuring device

Together, zincir ölçer refers to a specific kind of tool or device.

This is very normal in Turkish: many tool names and technical nouns are built from two parts like this.

Ölçer comes from the verb:

• ölçmek = to measure

The form ölçer can function as something like:

• measurer
• gauge
• meter

In compounds, it often names an instrument or device. So in zincir ölçer, it is the part that means a measuring tool.

There are two important things here:

1. Turkish has no articles

   • There is no exact equivalent of English a or the in many sentences.

2. Bare singular nouns can be generic

   • Turkish often uses the singular form to talk about a whole class of things in general.

So zincir ölçer here does not have to mean only one specific item.
It can mean a chain gauge or chain gauges in general, depending on context.

Yes. This is a normal Turkish order.

The sentence is:

• Zincir ölçer = subject/topic
• rublede = location/context phrase
• kullanılmaz = verb

Turkish usually puts the verb at the end, so this structure is very natural.

A different order is possible for emphasis, but the final verb position is the usual pattern.

A few letters here are especially important:

• ö = a front rounded vowel, somewhat like German ö or French eu
• ç = ch as in church
• ı = the Turkish dotless i, a sound English does not have exactly; it is somewhat like the weak vowel in sofa, but not the same

Roughly:

• ölçer ≈ OEL-cher
• kullanılmaz ≈ kool-lah-NIL-maz with the Turkish ı in -nıl-

The stress and exact vowels matter, but those approximations can help you get close at first.
