Das Kind ist gelangweilt.

In German, langweilig means boring (describes something that causes boredom), while gelangweilt means bored (describes the person who feels boredom).

• Das Kind ist langweilig. = The child is boring. (not very nice!)
• Das Kind ist gelangweilt. = The child is bored.

So gelangweilt is the correct form when you want to say how the child feels.

Gelangweilt is formally a past participle (Partizip II) of the verb langweilen, but in this sentence it is used as an adjective.

Structure:

• langweilen → gelangweilt (Partizip II)
• With sein
  • Partizip II, it becomes a stative description: a state the subject is in.

So in Das Kind ist gelangweilt, gelangweilt works like an adjective that describes the state of das Kind.

The ge- is the usual prefix used to form many German past participles.

Verb:

• langweilen → participle: ge
  • langweil
    • t = gelangweilt

This is the standard pattern for regular verbs:

• machen → gemacht
• lernen → gelernt
• spielen → gespielt

In our sentence, that participle is used adjectivally: ist gelangweilt.

Because Kind is a neuter noun in German.

• Gender of Kind: das Kind (neuter)
• Nominative singular definite articles:
  • der = masculine
  • die = feminine
  • das = neuter

Since Kind is neuter, you must use das in the nominative: Das Kind ist gelangweilt.

In German, all nouns are capitalized, no matter where they occur in the sentence.

• das Kind
• die Frau
• der Tisch
• die Langeweile

So Kind is capitalized simply because it is a noun, not because it is special in some other way.

Not in this position.

There are two main positions for adjectives/participles:

1. Predicative (after sein, werden, bleiben):

   • Das Kind ist gelangweilt.
   • No ending change; it stays gelangweilt for all genders and numbers:
     • Der Mann ist gelangweilt.
     • Die Frau ist gelangweilt.
     • Die Kinder sind gelangweilt.

2. Attributive (directly before a noun):

   • Here it does take an ending:
     • das gelangweilte Kind
     • ein gelangweiltes Kind
     • die gelangweilten Kinder

So: in our sentence (predicative use), gelangweilt does not change.

Yes, there is a nuance:

• Das Kind ist gelangweilt.

  • Focus on the state of the child.
  • The child is in a bored condition right now.

• Das Kind langweilt sich.

  • Literally: The child bores itself.
  • Focus on the ongoing process or experience of being bored; what the child is doing/feeling at the moment.

In many everyday contexts, both can be translated as The child is bored, but:

• ist gelangweilt = description of state
• langweilt sich = description of activity/experience

The base (infinitive) verb is langweilen.

• Infinitive: langweilen (to bore)
• Past participle: gelangweilt

Common forms:

• Ich langweile mich. = I am bored / I am getting bored.
• Der Film langweilt mich. = The film bores me.
• Ich bin gelangweilt. = I am bored. (state)

Yes, that is correct and very natural.

• Das Kind ist von der Aufgabe gelangweilt.
  = The child is bored by the task.

Here:

• von introduces what causes the boredom.
• Pattern: jemand ist von etwas gelangweilt
  • Ich bin von diesem Film gelangweilt.
  • Wir sind von dem langen Vortrag gelangweilt.

Yes, ist gelangweilt is present tense (ist = 3rd person singular of sein).

To put it into the (narrative) past:

• Das Kind war gelangweilt.
  = The child was bored.

You just change ist → war (preterite of sein). The participle gelangweilt stays the same.

Plural of das Kind is die Kinder.

Singular:

• Das Kind ist gelangweilt. = The child is bored.

Plural:

• Die Kinder sind gelangweilt. = The children are bored.

Changes:

• das Kind → die Kinder
• ist (singular) → sind (plural)
• gelangweilt stays the same.

Rough guide in IPA: [ɡəˈlaŋvaɪlt]

Syllables (roughly): ge-lang-weilt

• ge-: like guh- in guitar, but shorter and unstressed.
• lang-: like lung but with a as in father and a clear ng.
• weilt:
  • w like English v.
  • ei like eye.
  • final lt pronounced together, not very strong on the t.

So roughly: guh-LANG-vylt.
