Söguþráðurinn var fyrirsjáanlegur.

A word-for-word breakdown is:

• Söguþráðurinn = the plot / the storyline
• var = was
• fyrirsjáanlegur = predictable

The dictionary forms are:

• söguþráður = plot, storyline
• vera = to be
• fyrirsjáanlegur = predictable

Because Icelandic usually puts the definite article on the end of the noun instead of using a separate word like English the.

• söguþráður = plot / storyline
• söguþráðurinn = the plot / the storyline

So -inn here is the definite article attached to a masculine singular noun in the nominative.

Yes. It is a compound:

• saga = story
• þráður = thread

So the literal idea is something like story-thread, which is why it means plot or storyline.

The first part appears as sögu-, which is a common compound form. Learners do not need to translate it literally every time, but it can help you remember the word.

Because the adjective has to agree with söguþráðurinn in gender, number, and case.

Here, söguþráðurinn is:

• masculine
• singular
• nominative

So the adjective is also masculine singular nominative:

• fyrirsjáanlegur

If the noun changed, the adjective would change too. For example:

• Sagan var fyrirsjáanleg. = The story was predictable.
• Plottið var fyrirsjáanlegt. = The plot was predictable.
• Söguþræðirnir voru fyrirsjáanlegir. = The plots were predictable.

That is a very common question.

After a verb like vera = to be, Icelandic normally uses the strong form of the adjective in predicate position:

• Söguþráðurinn var fyrirsjáanlegur.

But when the adjective comes directly before a definite noun, Icelandic usually uses the weak form:

• fyrirsjáanlegi söguþráðurinn = the predictable plot

So:

• attributive adjective, before the noun: often weak
• predicative adjective, after vera: usually strong

That is why fyrirsjáanlegur is correct here.

Var is the past tense of vera = to be.

In this sentence, it means was.

A few useful related forms are:

• er = is
• var = was
• voru = were

So the present-tense version would be:

• Söguþráðurinn er fyrirsjáanlegur. = The plot is predictable.

Yes. Söguþráðurinn is the subject, so it is in the nominative case.

Because fyrirsjáanlegur is a predicate adjective after vera, it also agrees with the subject in:

• case
• number
• gender

So both are nominative singular masculine here.

This is very normal in Icelandic: predicate adjectives agree with the noun they describe.

This is the most neutral order:

• Söguþráðurinn var fyrirsjáanlegur.

But Icelandic word order is more flexible than English, especially because of the language’s case system and the verb-second pattern.

For emphasis or style, you could also see something like:

• Fyrirsjáanlegur var söguþráðurinn.

That is more marked or literary. A normal learner should use the original order unless there is a reason to emphasize something.

The trickiest letters here are usually these:

• þ as in þráður: like th in thing
• ð as in þráður: like th in this, often softer
• á: roughly like ow in cow
• ö: no exact English equivalent, but somewhat like a rounded vowel in words like British burn

So in söguþráðurinn, pay special attention to:

• þr at the start of þráður
• the contrast between þ and ð

You do not need perfect pronunciation immediately, but it is important to remember that þ and ð are different letters and sounds.

You usually put ekki = not after the verb:

• Söguþráðurinn var ekki fyrirsjáanlegur. = The plot was not predictable.

That is the normal way to negate this kind of sentence.

Yes. In many contexts, söguþráður can be translated as either plot or storyline.

Which English word sounds better depends on context:

• in a film or book review, plot is often the most natural translation
• when talking more loosely about how the story develops, storyline may fit better

So the Icelandic word is slightly flexible, just like many similar words in English.
