Das Preisschild fehlt.

Here, fehlt means is missing or is absent.

So Das Preisschild fehlt. means that the price tag is not there, even though it should be there.

German fehlen often corresponds to English to be missing, not usually to miss in the emotional sense.

Because Preisschild is a neuter noun, so it takes das.

A very useful rule for compound nouns in German is:

• the last part decides the gender

Here:

• Preis = price
• Schild = sign / tag / label

Since das Schild is neuter, the whole compound is also neuter:

• das Preisschild

Because German very often combines nouns into one compound word.

So instead of writing something like price tag as two words, German typically writes:

• Preis
  • Schild = Preisschild

This is completely normal in German. English speakers often expect spaces, but German usually prefers one combined noun.

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

The structure is:

• Das Preisschild = the thing being talked about
• fehlt = is missing

So literally, the sentence works like:

• The price tag is missing

That is why the verb agrees with das Preisschild.

Because the subject, das Preisschild, is singular.

• das Preisschild fehlt = the price tag is missing
• die Preisschilder fehlen = the price tags are missing

So:

• singular subject → fehlt
• plural subject → fehlen

No, that is not correct for this meaning.

German fehlen does not usually work like English to miss.

English says:

• I’m missing the price tag

But German usually says:

• Das Preisschild fehlt. = The price tag is missing.
• Mir fehlt das Preisschild. = I am missing the price tag / I don’t have the price tag.

So with fehlen, the missing thing is often the grammatical subject, and the person affected can appear in the dative:

• Mir fehlt das Preisschild.

They are very close, but the focus is slightly different.

• Das Preisschild fehlt.
  Focus: the price tag itself is missing.

• Mir fehlt das Preisschild.
  Focus: I am the person who does not have it / who notices its absence.

So the first is a general statement about the object. The second brings in the person affected.

Because in normal German, the verb fehlen is the natural choice.

• Das Preisschild fehlt. = normal, idiomatic
• Das Preisschild ist fehlend. = unnatural in everyday German

The adjective/participle fehlend does exist, but it is used more in phrases like:

• die fehlenden Unterlagen = the missing documents
• ein fehlender Knopf = a missing button

For a full sentence like this, fehlt is the standard way to say it.

Because all nouns are capitalized in German.

So:

• das = article, normally not capitalized unless it starts the sentence
• Preisschild = noun, always capitalized
• fehlt = verb, not capitalized

In this sentence, Das is capitalized only because it is the first word of the sentence.

Yes. It always means that the price tag is not there, but the exact situation depends on context.

For example, it could mean:

• the tag was never attached
• the tag fell off
• someone removed it
• it should be there, but it is absent

The sentence itself does not explain why it is missing. It only states the result.

You would say:

• Die Preisschilder fehlen. = The price tags are missing.

Changes:

• das Preisschild → die Preisschilder
• fehlt → fehlen

So both the noun and the verb change.

A common way is:

• Das Preisschild hat gefehlt. = The price tag was missing.

In everyday speech, people might also say:

• Das Preisschild war nicht da. = The price tag wasn’t there.

Both can work, but hat gefehlt stays closer to the original verb fehlen.

Approximately:

• Preisschild ≈ PRICE-shilt
• fehlt ≈ failt

A rough full pronunciation is:

• das PRICE-shilt failt

A few useful notes:

• ei in Preis sounds like English eye
• sch sounds like English sh
• eh in fehlt is a long e sound

So the sentence is fairly straightforward to pronounce once you know those sound patterns.
