Vi brukar jämföra priser innan vi köper biljetter.

Brukar means something like usually, tend to, or normally do.

So Vi brukar jämföra priser means:

• We usually compare prices
• We tend to compare prices

It describes a habit or something that happens regularly, not something happening right now.

In Swedish, bruka is followed directly by the infinitive, with no att.

So you say:

• Vi brukar jämföra priser
• not Vi brukar att jämföra priser

This is similar to some English verb patterns, like can go rather than can to go.

Jämföra is the infinitive form of the verb, meaning to compare.

After brukar, Swedish uses the infinitive:

• brukar jämföra = usually compare

Other examples:

• Jag brukar läsa på kvällen = I usually read in the evening
• De brukar komma tidigt = They usually arrive early

Because innan vi köper biljetter is a full subordinate clause: before we buy tickets.

Here, vi is the subject, so the verb must be a finite verb:

• vi köper = we buy

You would use the infinitive köpa only in structures like:

• innan vi ska köpa biljetter = before we are going to buy tickets
• för att köpa biljetter = in order to buy tickets

So in your sentence, innan vi köper biljetter is correct because it means before we buy tickets.

Swedish often uses the present tense in subordinate clauses like this when talking about something habitual or general.

• innan vi köper biljetter literally: before we buy tickets

That matches English quite well. Swedish does not need a special form like before buying here. A normal present-tense clause is very common and natural.

Since the whole sentence is about habit (brukar), the clause also has a general, habitual meaning.

Because after innan, Swedish starts a subordinate clause, and subordinate clauses usually keep the normal order:

• subject + verb
• vi köper

So:

• innan vi köper biljetter = before we buy tickets

If there were a sentence adverb like inte, you would see the typical subordinate-clause word order more clearly:

• innan vi inte köper... would be structurally subordinate, though not a natural sentence here
• compare main clause: Vi köper inte biljetter
• subordinate clause: innan vi inte köper...

The important point is that innan introduces a subordinate clause.

Innan usually means before and often introduces a clause:

• innan vi köper biljetter = before we buy tickets

Före is also often translated as before, but it is commonly used before a noun or noun phrase:

• före köpet = before the purchase
• före resan = before the trip

In many cases, both can appear, but innan is especially common before a full clause with a subject and verb.

So in this sentence, innan is the most natural choice.

Because the idea is that you compare different prices from different options.

• pris = price
• priser = prices

This is very natural in both Swedish and English:

• compare prices

If you said jämföra pris, it would sound incomplete or unusual in most contexts.

Biljetter is the indefinite plural form: tickets.

• en biljett = a ticket
• biljetter = tickets
• biljetterna = the tickets

In this sentence, the meaning is general, not specific:

• before we buy tickets

It is not referring to particular already-known tickets, so biljetter is the natural form.

Because Swedish does not use a marker like English to before every verb. The infinitive form itself is enough in many constructions.

Here:

• jämföra = to compare

But after brukar, Swedish uses the bare infinitive:

• brukar jämföra

So English needs to compare in dictionary form, but Swedish simply uses jämföra.

Usually, no.

Vi brukar jämföra priser means:

• We usually compare prices
• We tend to compare prices

But we are used to means something different: being accustomed to something.

For be used to, Swedish would more likely use expressions like:

• vi är vana vid att... = we are used to...

So:

• Vi brukar jämföra priser = habitual action
• Vi är vana vid att jämföra priser = we are accustomed to comparing prices

They are related ideas, but not the same.

You can say:

Innan vi köper biljetter brukar vi jämföra priser.

That is also correct and natural.

Notice the word order in the main clause after the fronted subordinate clause:

• brukar vi
• not vi brukar

This happens because Swedish main clauses usually follow the V2 rule: the finite verb comes in the second position.

So:

• Vi brukar jämföra priser innan vi köper biljetter.
• Innan vi köper biljetter brukar vi jämföra priser.

Both are correct, just with different emphasis.

A rough guide is: YEM-fuh-ra.

A few helpful points:

• j in Swedish is often like English y
• ä sounds somewhat like the e in bed, though not exactly
• ö is a rounded vowel that English does not really have
• the stress is on the first syllable: JÄMföra

So an approximate pronunciation is:

• YEM-fur-a or YEM-fuh-ra

It is only an approximation, but it helps you get started.
