Leikslokin eru nálægt.

Leikslokin is a compound form:

• leik- / leiks- from leikur
• lok meaning end, conclusion
• -in, the suffixed definite article

So the structure is basically leiks + lok + in. The s is a linking consonant that often appears in compounds.

In Icelandic, the definite article is usually attached to the end of the noun instead of being a separate word.

So:

• leikslok = end of the game/play in an indefinite sense
• leikslokin = the end of the game/play

That final -in is the equivalent of English the here.

Because leikslokin is grammatically plural, and the verb vera must agree with it.

• er = is for singular
• eru = are for plural

So Icelandic says Leikslokin eru nálægt, even though English often uses singular wording such as The end is near.

Yes, grammatically it is treated as plural.

This is very common with lok and related words in Icelandic. They often refer to an ending or conclusion but still behave like a plural noun. So this is one of those cases where English and Icelandic do not match neatly:

• English: the end is near
• Icelandic: leikslokin eru nálægt

A good strategy is to memorize leikslok as a plural noun.

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

The verb eru tells you what the subject is doing or being, and leikslokin is the thing being described as nálægt.

So this form is nominative plural definite.

Here nálægt means near or close at hand.

In this sentence it is used after vera in a predicate-like way:
Leikslokin eru nálægt = The end is near

Nálægt is handy because it can also be used as a preposition with the dative:

• nálægt húsinu = near the house

But in your sentence, there is no following noun, so it simply means near.

Yes. Leikur can mean several related things depending on context, including:

• game
• match
• play in a theatrical sense

So leikslok can refer to the end of the game, the end of the match, or the end of the play, depending on the situation.

Yes. Leikslokin eru nálægt is the normal, neutral word order:

• subject: Leikslokin
• verb: eru
• predicate/complement: nálægt

If you turn it into a question, the verb comes first:

• Eru leikslokin nálægt? = Is the end near?

So the original sentence has standard, straightforward Icelandic word order.
