Hún var heiðarleg þó að svarið væri erfitt að heyra.

Þó að means although / even though. It introduces a concessive clause, meaning a clause that contrasts with the main statement.

So the sentence has:

• main clause: Hún var heiðarleg = she was honest
• subordinate clause: þó að svarið væri erfitt að heyra = even though the answer was hard to hear

You may also see the related form þótt, which often means the same thing.

Because þó að commonly takes the subjunctive in Icelandic.

• var = past indicative of vera = was
• væri = past subjunctive of vera

After conjunctions like þó að, Icelandic often uses the subjunctive to mark the subordinate clause. So:

• Hún var heiðarleg = main statement, indicative
• þó að svarið væri erfitt að heyra = subordinate concessive clause, subjunctive

To an English speaker, this can feel unfamiliar because English usually does not show this distinction clearly.

Both come from the verb vera = to be, but they are different moods.

• var = past indicative, used for straightforward factual statements
• væri = past subjunctive, often used after certain conjunctions, in hypothetical contexts, and in reported or less direct situations

In this sentence:

• var is used in the main clause: Hún var heiðarleg
• væri is used in the clause introduced by þó að

So the contrast is grammatical, not a change in basic meaning.

Svarið is the definite form of svar.

• svar = an answer
• svarið = the answer

The ending -ið marks the neuter singular definite form here.

So:

• svarið væri erfitt að heyra = the answer was hard to hear

Svarið is in the nominative case because it is the subject of the subordinate clause.

In svarið væri erfitt að heyra:

• svarið = subject
• væri = verb
• erfitt = predicate adjective

Since it is the subject, nominative is the expected case.

Because it describes hún, which means she.

Icelandic adjectives agree with the noun or pronoun they describe in gender, number, and case. Here:

• hún = feminine singular
• heiðarleg = feminine singular form of heiðarlegur = honest

So Hún var heiðarleg means She was honest, with the adjective matching a feminine subject.

Because it agrees with svarið, which is a neuter singular noun.

• svar is neuter
• definite form: svarið
• adjective form used with it: erfitt

So:

• svarið væri erfitt = the answer was difficult

This is standard adjective agreement:

• masculine: different form
• feminine: different form
• neuter: erfitt

Að heyra is the infinitive to hear.

In erfitt að heyra, the pattern means hard to hear or difficult to hear.

This is a very common Icelandic structure:

• gaman að lesa = fun to read
• erfitt að skilja = hard to understand
• leiðinlegt að bíða = boring to wait

So svarið væri erfitt að heyra literally means the answer would be difficult to hear, but naturally in English we say the answer was hard to hear.

The two instances of að do different jobs.

1. þó að

   • here að is part of the conjunction þó að = although / even though

2. að heyra

   • here að is the infinitive marker = to hear

So even though the same word appears twice, it is not the same grammatical function both times.

Yes, but it is normal Icelandic subordinate-clause word order.

Inside the subordinate clause, you get:

• svarið = subject
• væri = verb
• erfitt = complement
• að heyra = infinitive phrase

After a subordinating conjunction like þó að, Icelandic does not use the main-clause V2 pattern in the same way. So the clause looks more straightforwardly like subject + verb + complement.

That is why:

• þó að svarið væri erfitt að heyra not something like
• þó að væri svarið erfitt að heyra

Yes. Þótt often means the same as þó að.

So a very similar sentence would be:

• Hún var heiðarleg þótt svarið væri erfitt að heyra.

That is a normal alternative. Both forms are common, though style and frequency can vary by speaker and context.

It can mean either, depending on context, but in a sentence like this it is very likely emotionally difficult to hear.

Since the first clause is Hún var heiðarleg, the idea is probably:

• she told the truth
• but the truth was unpleasant or painful to hear

So the phrase often works like English hard to hear in an emotional sense, not just an acoustic one.

You can get close, but a fully natural English translation will usually be less literal.

A very literal breakdown is:

• Hún = she
• var = was
• heiðarleg = honest
• þó að = although / even though
• svarið = the answer
• væri = were / was (subjunctive)
• erfitt = difficult / hard
• að heyra = to hear

So literally:

• She was honest although the answer were hard to hear

That is not natural English because English does not usually keep the same subjunctive distinction here. A natural translation is:

• She was honest even though the answer was hard to hear.

Here are the main dictionary forms:

• hún = she
• vera = to be
• heiðarlegur = honest
• þó að = although / even though
• svar = answer
• erfiður = difficult, hard
• heyra = hear

This is useful because the actual sentence uses inflected forms:

• var from vera
• væri from vera
• heiðarleg from heiðarlegur
• svarið from svar
• erfitt from erfiður
• heyra already appears in dictionary form after að
