Die Türklinke im Bad ist kalt.

Because Türklinke is a feminine noun in German, so it takes the nominative singular article die.

• die Türklinke = the door handle

In German, grammatical gender is something you usually have to learn together with the noun:

• der = masculine
• die = feminine
• das = neuter

So it is best to learn it as die Türklinke, not just Türklinke.

Türklinke is a compound noun:

• Tür = door
• Klinke = handle / latch

So Türklinke literally means door handle.

German very often combines nouns into one longer noun, so this is a very normal structure.

German often joins nouns directly to make a compound noun. The first noun usually keeps its basic form.

So:

• die Tür
  • die Klinke → die Türklinke

This is similar to English compounds like door handle, except German usually writes them as one word.

im is a contraction of in dem.

• in dem Bad → im Bad

So im Bad means in the bathroom.

This contraction is extremely common in German. You will often see:

• im = in dem
• am = an dem
• vom = von dem
• zum = zu dem

Because this sentence describes location, not movement.

• im Bad = in the bathroom (where something is)
• ins Bad = into the bathroom (movement toward it)

Here, the sentence says where the door handle is located: in the bathroom. So German uses the dative:

• in dem Bad → im Bad

If there were movement, you would use the accusative:

• Ich gehe ins Bad. = I am going into the bathroom.

Because all nouns are capitalized in German.

So in this sentence:

• Türklinke is capitalized
• Bad is capitalized

This is one of the most noticeable spelling differences between German and English.

In everyday German, das Bad very often means bathroom.

Literally, Bad can relate to bath, but in normal usage:

• im Bad usually means in the bathroom

You may also hear:

• das Badezimmer = bathroom

Both are possible, but Bad is very common and natural in everyday speech.

Because German main clauses usually follow the verb-second rule.

The basic structure here is:

• Die Türklinke = subject
• ist = verb
• kalt = complement
• im Bad = location phrase

In a normal statement, the finite verb usually comes in second position:

• Die Türklinke im Bad ist kalt.

If another element comes first, the verb still stays second:

• Im Bad ist die Türklinke kalt.

So the verb’s position is a key feature of German sentence structure.

Because kalt here is a predicate adjective, not an adjective directly in front of a noun.

Compare:

• Die Türklinke ist kalt.
  Here kalt comes after the verb ist, so it does not take an ending.

• die kalte Türklinke
  Here the adjective comes before the noun, so it does take an ending.

This is similar to English:

• the cold door handle
• the door handle is cold

German changes the adjective only in the first type.

In this sentence, kalt means physically cold to the touch.

German kalt can also be used in other ways, for example:

• kaltes Wetter = cold weather
• eine kalte Stimme = a cold voice / emotionally cold tone

But with Türklinke, the natural meaning is simply that the handle feels cold.

Yes. That is also correct.

Both are grammatical:

• Die Türklinke im Bad ist kalt.
• Im Bad ist die Türklinke kalt.

The difference is mainly emphasis:

• Die Türklinke im Bad ist kalt.
  Starts with the thing being talked about: the door handle in the bathroom

• Im Bad ist die Türklinke kalt.
  Starts with the location: in the bathroom

German lets you move elements around more freely than English, but the finite verb still normally stays in second position.

A rough pronunciation guide is:

• Tür sounds somewhat like tewr but with rounded lips
• Klinke sounds like KLIN-kuh

So: TÜRK-link-uh

A few helpful points:

• ü does not exist in standard English; it is a rounded front vowel
• r after a vowel in many accents of German is not strongly pronounced
• the stress is on the first part: TÜRKlinke

Because kalt is an adjective, not a noun.

Articles like der, die, das, ein, eine go with nouns:

• die Türklinke
• das Bad

But kalt is just describing the noun after the verb:

• Die Türklinke ist kalt.

So no article is needed.

It is in the nominative case, because it is the subject of the sentence.

You can identify the subject by asking: what is cold?

• Die Türklinke is cold.

So:

• die Türklinke = nominative subject
• im Bad = dative after in for location

This is a good example of how one sentence can contain more than one case.
