Fyrsta atriðið í skýrslunni var auðvelt, en annað atriði þurfti meiri útskýringu.

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

• atriði = item, point
• atriðið = the item, the point

Here atriðið is neuter singular definite.

The first phrase is clearly definite: fyrsta atriðið = the first item.

The second phrase is indefinite in form: annað atriði = literally another item or a second item. In context, it may still be understood as the next point in the report, but grammatically it is not marked definite in the same way as atriðið.

If you wanted a fully parallel definite phrase, you would normally expect annað atriðið.

Because adjectives and ordinal numbers in Icelandic have to agree with the noun in gender, number, and case.

The noun atriði is:

• neuter
• singular
• nominative here, because it is the subject

So the ordinal fyrstur appears here as fyrsta, the form that matches this noun in this context.

Also, ordinals are often weak when used with a definite noun, which is why fyrsta fits well with atriðið.

Annað is the neuter singular form of annar.

This word can mean things like:

• second
• another
• other

Because atriði is a neuter singular noun, the matching form is annað.

So:

• annar = masculine form
• önnur = feminine form
• annað = neuter form

Because í takes the dative when it means location, as in in the report.

Here the meaning is location, not movement, so Icelandic uses dative:

• skýrsla = report
• skýrslunni = in the report / the report, dative singular definite

A useful rule is:

• í + dative = in, inside, located in
• í + accusative = into, movement into

Because it is a predicate adjective after var, and predicate adjectives agree with the subject.

The subject is fyrsta atriðið, and atriði is neuter singular, so the adjective must also be neuter singular:

• auðveldur = masculine
• auðveld = feminine
• auðvelt = neuter

So atriðið var auðvelt means the adjective is matching atriðið.

They are both past tense forms.

• var = was, from vera
• þurfti = needed, from þurfa

So the sentence is describing two things in the past:

• the first item was easy
• the second/another item needed more explanation

Because each half of the sentence has its own subject.

First clause:

• Fyrsta atriðið ... var auðvelt

Second clause:

• annað atriði ... þurfti meiri útskýringu

So þurfti only agrees with annað atriði, which is singular.

Meiri means more. It is the comparative form of mikill, which means much or great.

Here it describes útskýringu, and that noun is feminine singular accusative, so meiri is the matching form.

Compare:

• meiri útskýring / meiri útskýringu with feminine forms
• meira is often used with neuter singular or adverbially

So meiri útskýringu = more explanation.

It is the accusative singular of útskýring, which is a feminine noun meaning explanation.

That happens because þurfa normally takes a direct object in the accusative:

• þurfa eitthvað = to need something

So:

• útskýring = explanation
• útskýringu = explanation, accusative singular

That is why the sentence has þurfti meiri útskýringu.

It can mean several related things depending on context, including:

• item
• point
• issue
• detail

In a sentence about a report, atriði often feels very natural as point or item. So this is a useful word to learn as a fairly broad term for a unit in a discussion, list, or document.
