Veröndin er stór.

The -in is the definite article attached to the noun. Icelandic often says the by adding it to the end of the word instead of using a separate word like English does.

So:

• verönd = veranda / porch
• veröndin = the veranda / the porch

This is very common in Icelandic. Compare:

• bíll = car
• bíllinn = the car

So in this sentence, the noun is definite: veröndin.

Er is the present tense, third person singular form of the verb að vera (to be).

That means it is used with singular subjects like:

• hann er = he is
• hún er = she is
• húsið er = the house is
• veröndin er = the veranda is

A few useful forms of að vera are:

• ég er = I am
• þú ert = you are
• hann / hún / það er = he / she / it is
• við erum = we are
• þið eruð = you are
• þeir / þær / þau eru = they are

So er is exactly the form you expect here.

Because adjectives in Icelandic agree with the noun they describe in gender, number, and case.

Here, veröndin is:

• feminine
• singular
• nominative

So the adjective also appears in the matching form: stór.

A useful comparison:

• stór verönd = a big veranda
• veröndin er stór = the veranda is big

Even though veröndin is definite (the veranda), the adjective after er is still used in the appropriate predicate form. Icelandic does not do what English does with an unchanging adjective; instead, the adjective still agrees with the noun.

Compare with other genders:

• bíllinn er stór = the car is big (masculine)
• húsið er stórt = the house is big (neuter)

So stór here is the correct agreeing form for a feminine singular subject.

Yes. This is a very normal basic sentence pattern:

• Subject + verb + adjective

So:

• Veröndin = subject
• er = verb
• stór = predicate adjective

This is the straightforward equivalent of English The veranda is big.

Icelandic word order can change in some situations, especially when another element comes first, but this sentence is completely standard and natural.

A learner will usually notice two letters here: ö and ð.

ö

Ö is not like English o. It is closer to:

• German ö
• French eu in some words

It is a rounded front vowel. English does not have an exact match.

ð

Ð / ð is usually like the th in this, not like the th in thing.

So veröndin contains that soft voiced th sound.

ó

In stór, the ó is a long vowel, roughly like o in go, but purer and more rounded.

Rough learner-friendly approximation

A rough pronunciation guide might be:

• veröndin ≈ veh-RUN-thin / veh-RERN-thin
• stór ≈ store but with a purer long o

That said, English spellings are only approximations. The most important sounds to pay attention to are ö, ð, and long ó.

Because Icelandic usually puts the definite article onto the noun itself.

So instead of a separate word like English the, Icelandic often uses an ending:

• verönd = veranda
• veröndin = the veranda

This is one of the big differences between English and Icelandic grammar.

You can also see forms involving a separate demonstrative-like word in some contexts, but for ordinary definite nouns, the suffixed article is the normal pattern.

Yes, but that means something slightly different in structure.

• Veröndin er stór. = The veranda is big.

  • Here stór is a predicate adjective after er.

• Stóra veröndin = the big veranda

  • Here stóra is an attributive adjective directly modifying the noun.

That difference matters in Icelandic, because adjective forms often change depending on how they are used.

So:

• Veröndin er stór. = full sentence
• stóra veröndin = noun phrase, not a full sentence by itself

Yes, verönd is feminine.

In this sentence, you usually know that from vocabulary knowledge or a dictionary entry, because Icelandic noun gender is something you generally need to learn along with the word.

A dictionary will often show it like this:

• verönd (f.)

The adjective agreement also fits a feminine singular noun here:

• veröndin er stór

But in practice, the safest way is: learn each noun with its gender.

That is very important in Icelandic, because gender affects:

• adjectives
• pronouns
• some number forms
• article and case patterns

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

In a simple sentence like this:

• Veröndin = the subject
• er stór = says something about the subject

Subjects are normally in the nominative in Icelandic.

So this sentence is a good example of a basic nominative subject with a predicate adjective.

In this sentence, yes, the most natural reading is physically large / big.

With a noun like verönd, stór would normally describe size.

More generally, stór can also mean things like:

• great
• large
• important

depending on context. But with a concrete object such as a veranda, the ordinary meaning is simply big or large.

Yes, verönd is a real Icelandic word meaning veranda / porch / balcony-like outdoor platform, depending on context.

It is also easy for English speakers to recognize because it resembles veranda. That resemblance is helpful, but you should still pay attention to the Icelandic grammar:

• the noun has grammatical gender
• the definite article is attached
• adjectives must agree

So even if the word looks familiar, it behaves in a distinctly Icelandic way.
