Upplýsingin er forskráð.

Because Icelandic usually attaches the definite article to the noun instead of using a separate word like English the.

• upplýsing = information / a piece of information
• upplýsingin = the information

So the -in ending here is the definite article.

Upplýsingin is:

• feminine
• singular
• nominative

It is nominative because it is the subject of the sentence. The dictionary form is upplýsing.

Because adjectives and participles in Icelandic must agree with the noun they describe.

Since upplýsingin is feminine singular nominative, the predicate word also has to match that noun. Here the matching form is forskráð.

Compare the idea:

• masculine singular: skráður
• feminine singular: skráð
• neuter singular: skráð

So forskráð is the correct agreeing form with upplýsingin.

It is historically a past participle of the verb forskrá, but in this sentence it functions very much like an adjective.

So in Upplýsingin er forskráð, it describes the state of the information: it is in a pre-registered / pre-entered state.

This is very common in Icelandic: a past participle is used with vera to describe a resulting state.

It is passive-like in meaning, but it is often best understood as describing a state.

• er = is
• forskráð = pre-registered / pre-entered

So the sentence means that the information is in the state of having been pre-registered.

For a learner, it is fine to think of it as similar to English is pre-registered, even though Icelandic grammar does not always line up perfectly with English passive grammar.

The word order is:

• Upplýsingin = subject
• er = verb
• forskráð = subject complement / predicative participle

So it follows a very normal Icelandic main-clause pattern:

subject + verb + complement

Also remember that Icelandic is a verb-second language. If another element comes first, the finite verb still usually stays in second position:

• Nú er upplýsingin forskráð. = Now the information is pre-registered.

Often upplýsing in the singular means a piece of information or one item/entry of information, while upplýsingar in the plural often means information in a broader sense.

So this sentence most naturally sounds like it is talking about:

• one specific information field
• one item in a system
• one entry on a form or in a database

That fits well with forskráð, which sounds administrative or technical.

You usually move the finite verb to the front:

• Upplýsingin er forskráð. = The information is pre-registered.
• Er upplýsingin forskráð? = Is the information pre-registered?

This verb-first pattern is very common for yes/no questions in Icelandic.

A rough learner-friendly guide is:

• Upplýsingin ≈ UP-lee-sing-in
• er ≈ ehr
• forskráð ≈ FOR-skrowth

A few useful points:

• The stress in Icelandic is normally on the first syllable.
• ý sounds roughly like English ee in see.
• á sounds like ow in now.
• Final ð is a very light th-like sound.

These are only rough approximations, but they are a reasonable starting point.
