Skoðunarvottorðið er tilbúið.

It is a very typical Icelandic compound noun. It can be broken down like this:

• skoðunar- = of inspection / inspection
• vottorð = certificate
• -ið = the suffixed definite article, meaning the

So skoðunarvottorðið means the inspection certificate.

The first part, skoðunar-, comes from skoðun and appears in the genitive form, which is very common in Icelandic compounds.

In Icelandic, the definite article is usually attached to the noun as a suffix.

So instead of having a separate word like English the, Icelandic often does this:

• vottorð = certificate
• vottorðið = the certificate

The same thing happens in skoðunarvottorðið: the final -ið means the.

This is one of the biggest structural differences from English.

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

In Skoðunarvottorðið er tilbúið, the thing doing the grammatical job of subject is the inspection certificate, so nominative is the expected form.

Er is the third-person singular 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

Since skoðunarvottorðið is a singular noun, Icelandic uses er.

Because the adjective has to agree with the noun in gender and number.

The noun vottorð is neuter singular, so the adjective also appears in the neuter singular form:

• masculine: tilbúinn
• feminine: tilbúin
• neuter: tilbúið

Since skoðunarvottorðið is neuter singular, tilbúið is the correct form.

Usually tilbúinn / tilbúin / tilbúið means ready.

In a sentence like this, it often has the practical sense of:

• ready
• prepared
• sometimes completed and ready for collection/use

So the exact English wording depends on context, but the core idea is that the certificate is now available or prepared.

Yes. This is a very normal sentence pattern:

• subject
  • verb
    • adjective/complement

So:

• Skoðunarvottorðið = subject
• er = verb
• tilbúið = complement

This is directly comparable to English The inspection certificate is ready.

Yes, Icelandic is more flexible with word order than English, and that kind of reordering is possible in some contexts. But it would sound more marked or stylistically shaped.

The most neutral, everyday wording is:

• Skoðunarvottorðið er tilbúið.

That is the form learners should treat as the basic pattern.

Yes, but the meaning changes.

• Skoðunarvottorðið er tilbúið. = The inspection certificate is ready.
• Skoðunarvottorð er tilbúið. = An inspection certificate is ready or inspection certificate is ready, depending on context

Without -ið, the noun is indefinite. In many real situations, the definite form is more natural because both speaker and listener know which certificate is being talked about.

The letter ð in Icelandic is usually like the th in English this, not like the th in thing.

So:

• -ðið has a sound roughly like thith or thid, depending on the speaker and exact environment

A few pronunciation notes:

• ó is a distinct vowel, roughly like oh
• ú is roughly like oo
• í is roughly like ee
• ð is a voiced th
• the final -ið in tilbúið is pronounced as part of the neuter ending

Exact pronunciation varies a bit by speaker, but those approximations are a good start.

Because Icelandic often uses the genitive form in compounds.

The base noun is skoðun. In the compound, it becomes skoðunar-, which is the genitive singular form. This is a very common way to build compound nouns in Icelandic.

So the structure is essentially:

• certificate of inspection
  rather than
• inspection certificate as English would more naturally phrase it

Even though English and Icelandic express it differently, the result is the normal Icelandic compound skoðunarvottorð.

Yes, vottorð is a neuter noun, and yes, you should memorize noun gender in Icelandic.

Gender matters because it affects:

• adjective forms
• pronouns
• article endings
• some declension patterns

Here, knowing that vottorð is neuter helps explain both:

• vottorðið with the neuter definite ending
• tilbúið in the neuter singular form

So when learning vocabulary, it is very useful to learn the noun together with its gender.
