Hjálpartækið er tilbúið.

They are:

• hjálpartæki = the noun
• vera = to be; the form here is er
• tilbúinn = ready / prepared; the form here is tilbúið

So the sentence uses inflected forms, not the bare dictionary forms.

Hjálpartækið is a single noun, and Icelandic usually writes this kind of compound as one word.

It breaks down like this:

• hjálpar- = help / assistance
• tæki = device, tool, piece of equipment
• -ið = the suffixed definite article, here meaning the

So:

• hjálpartæki = assistive device / aid
• hjálpartækið = the assistive device / the aid

Unlike English, Icelandic often puts the at the end of the noun instead of using a separate word.

Here it is:

• gender: neuter
• number: singular
• case: nominative

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

A useful point: the basic form hjálpartæki can look a little tricky, because some neuter nouns have the same form in singular and plural in certain cases. But here hjálpartækið is clearly singular, and the verb er also confirms that.

Er is the present singular form of vera = to be.

Because the subject is singular, Icelandic uses:

• er = is

If the subject were plural, you would use:

• eru = are

So Hjálpartækið er tilbúið follows the same basic pattern as English The device is ready.

Because tilbúið is agreeing with a neuter singular subject.

The adjective’s dictionary form is tilbúinn, but adjectives in Icelandic change form to match the noun they describe or refer to.

Here are the singular nominative forms:

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

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

No. They only look the same.

• In hjálpartækið, -ið is the definite article: the
• In tilbúið, -ið is an adjective ending showing neuter singular

So the two endings have different jobs:

• hjálpartæki + ið = the device
• tilbúi-ð = adjective form matching a neuter singular noun

This is a very common thing in Icelandic: endings may look alike but have different grammatical functions.

Because tilbúið is a predicate adjective, not an adjective directly placed before the noun.

In Icelandic, adjectives after vera usually stay in the strong form, even if the noun is definite.

So you say:

• Hjálpartækið er tilbúið. = predicate adjective after er

But if the adjective came directly before the noun, you would use a different form:

• tilbúna hjálpartækið = the ready device

So:

• after to be: tilbúið
• directly before the definite noun: tilbúna

That difference is very important in Icelandic grammar.

A rough English-friendly guide would be:

• Hjálpartækið ≈ HYAL-par-tie-kith
• er ≈ ehr
• tilbúið ≈ til-BOO-ith

A few helpful pronunciation notes:

• hj at the start is not exactly normal English h; it has a softer, more palatal sound
• æ is roughly like eye
• ð is like the th in this, though at the end of a word it can sound weaker
• stress in Icelandic usually falls on the first syllable

So the whole sentence is roughly:

HYAL-par-tie-kith ehr til-BOO-ith

The normal, neutral order is:

• Hjálpartækið er tilbúið.
• subject + verb + complement

That is the most natural order for a simple statement.

Icelandic does allow other orders for emphasis, because it is a verb-second language, but those alternatives are more marked. For a learner, the safest pattern is the one in your sentence.

So this sentence is a very standard model to copy.

It is a compound noun built from:

• hjálp = help
• a linking form hjálpar-
• tæki = device, tool, equipment

So literally it is something like help-device or assistance-device.

That kind of compound is extremely common in Icelandic. Learning to notice the parts inside long words is very useful, because it helps you guess meanings and remember vocabulary.
