Endirinn er ekki góður.

Endirinn = endir + -inn

• endir = end / ending
• -inn = the suffixed definite article, meaning the

So endirinn means the end or the ending.

This is very common in Icelandic: instead of putting a separate word for the before the noun, Icelandic usually attaches it to the noun itself.

Because Icelandic normally expresses the by attaching it to the noun.

So:

• endir = an end / end
• endirinn = the end

This is different from English, but it is one of the most basic patterns in Icelandic. The definite article changes form depending on gender, number, and case.

Er is the present tense of vera, which means to be.

So:

• ég er = I am
• þú ert = you are
• hann/hún/það er = he/she/it is

In Endirinn er ekki góður, er simply means is.

In a normal Icelandic statement, ekki (not) usually comes after the finite verb.

So the pattern is:

• subject + verb + ekki
  • complement

Here:

• Endirinn = subject
• er = verb
• ekki = not
• góður = good

That is why Icelandic says:

• Endirinn er ekki góður

rather than putting ekki before the verb, as English often does in a different structure.

Because Icelandic adjectives must agree with the noun they describe.

Endirinn is:

• masculine
• singular
• nominative

So the adjective also appears in the masculine singular nominative form:

• góður

Compare:

• masculine: góður
• feminine: góð
• neuter: gott

So if the noun were neuter, you would not use góður.

Because this is a sentence with vera (to be), where the adjective is a predicate adjective.

In sentences like X is good, Icelandic normally uses the nominative for the subject, and the predicate adjective agrees with that subject.

So:

• Endirinn is nominative
• góður is also nominative to match it

This is different from situations where an adjective directly modifies a noun inside a noun phrase, but the agreement idea is the same.

Not if you are referring to endirinn.

Gott is the neuter form of the adjective. But endir is masculine, so you need the masculine form:

• correct: Endirinn er ekki góður
• not correct here: Endirinn er ekki gott

A quick comparison:

• maðurinn er góður = the man is good
• konan er góð = the woman is good
• húsið er gott = the house is good

Not always.

Ekki góður literally means not good, which can be softer or less direct than bad.

Depending on context, it might suggest:

• disappointing
• unsatisfying
• not very good
• problematic

So Endirinn er ekki góður may sound slightly more cautious or understated than a fully direct statement like The ending is bad.

Yes, but Endirinn er ekki góður is the most neutral and straightforward order.

Icelandic allows word order variation more than English, especially for emphasis. For example, other orders may appear in speech or literature, but they usually add emphasis or sound marked.

For a learner, the safest default is:

• Endirinn er ekki góður.

That is the standard, neutral way to say it.

A rough learner-friendly guide is:

• Endirinn ≈ EN-di-rin
• er ≈ er
• ekki ≈ EHK-ki
• góður ≈ GOH-thur or GOH-dhur

A few helpful notes:

• ó is a long vowel, roughly like o in go, but not exactly the same.
• ð is a voiced sound like th in this.
• Double kk is pronounced clearly as a long/strong k sound.

This is only an approximation, but it can help you get started.

The indefinite version would be:

• Endir er ekki góður.

But in real usage, that sentence is less natural in many contexts unless you mean an ending in a general sense.

The key contrast is:

• endir = an end / ending
• endirinn = the end / the ending

So the original sentence is definite because it refers to a specific ending.
