Questions & Answers about Ávextirnir eru ferskir í dag, svo ég kaupi fleiri epli.

What does the -nir ending in Ávextirnir mean?

-nir is the definite article suffix attached to the noun.

• ávextir = fruits (indefinite)
• ávextirnir = the fruits (definite, plural)

It’s similar in meaning to adding the in English, but Icelandic usually attaches it to the end of the noun.

Why is it eru and not er?

Because the subject Ávextirnir is plural, the verb to be must also be plural:

• er = is (singular)
• eru = are (plural)

So Ávextirnir eru … = The fruits are …

Why does ferskur become ferskir here?

Predicate adjectives (adjectives after eru/er) still agree with the subject in number, gender, and case.

Here the subject is:

• ávextirnir = masculine plural nominative

So the adjective takes masculine plural nominative:

• ferskur (m. sg. nom.) → ferskir (m. pl. nom.)

Why isn’t it ferskirnir (with a definite ending) since the noun is definite?

In Icelandic, adjectives used as predicate adjectives (after verbs like to be) are normally not marked as definite, even if the noun is definite.

So you say:

• Ávextirnir eru ferskir. (The fruits are fresh.)
  not ferskirnir.

What does í dag mean grammatically, and why that form?

í dag means today and is a fixed, very common time phrase.

Literally it’s in day, where:

• í often governs the accusative for “time/extent” expressions,
• dag is the accusative of dagur (day).

You’ll also see related phrases like í gær (yesterday), í morgun (tomorrow / in the morning, depending on context).

What does svo do here, and why is there a comma before it?

Here svo functions like so / therefore, connecting two clauses:

• Ávextirnir eru ferskir í dag,
• svo ég kaupi fleiri epli.

The comma is common because you’re joining two full clauses (roughly like English: …, so I …).

Why is the verb form kaupi and not something like kaupa?

kaupi is the 1st person singular present tense form of að kaupa (to buy):

• (ég) kaupi = I buy / I am buying

kaupa is the infinitive (to buy) and can’t be used as the main finite verb of the sentence.

Note: kaupi has the same form in both indicative and subjunctive in modern Icelandic, but here it’s simply the normal present-tense “I buy”.

Does Icelandic require the pronoun ég, or can it be dropped?

Usually you keep subject pronouns like ég in normal statements.

You can omit it in some contexts (especially in informal speech, diaries, coordinated structures with clear reference, etc.), but as a learner it’s safest to include it:

• … svo ég kaupi … is the standard, clear choice.

Why is it fleiri and not meiri?

Both mean more, but they’re used differently:

• fleiri = more (in number) → used with countable plural nouns (more apples, more people)
• meiri = more (in amount/degree) → often used with mass nouns or abstract amount (more water, more time)

Since epli are countable items, fleiri epli = more apples.

What case is epli in after kaupa, and why doesn’t it change form?

að kaupa (to buy) typically takes a direct object in the accusative.

So epli here is accusative plural. It just looks unchanged because epli is a neuter noun whose nominative and accusative forms are identical:

• nom. pl.: epli
• acc. pl.: epli (Other cases do change: e.g., dative plural eplum, genitive plural epla.)

How is Ávextirnir pronounced (roughly), especially the first letter Á?

A rough guide:

• Á is pronounced like ow in cow (an au-like sound).
• Ávextirnir is roughly OW-vek-tir-nir (with Icelandic r and crisp consonants).

Also:

• epli is roughly EH-pli (with a clear p).
