Jag brukar hälla varmt vatten i min termos och ta med te med citron till jobbet.

Brukar is a very common way to talk about something you usually do or something you do habitually.

So Jag brukar ... means I usually ... or I tend to ...

It is not about what you are doing right now. It describes a routine or habit.

After bruka, Swedish normally uses the bare infinitive, without att.

So:

• Jag brukar hälla ...
• Jag brukar ta med ...

not:

• Jag brukar att hälla ...

This is similar to English verbs like can or must, which are also followed by a verb without to.

Because brukar applies to both infinitives in the coordinated phrase:

• hälla varmt vatten i min termos
• ta med te med citron till jobbet

So the sentence means:

• I usually pour hot water into my thermos and bring tea with lemon to work.

You could repeat brukar, but you normally do not need to:

• Jag brukar hälla varmt vatten i min termos och brukar ta med te med citron till jobbet.

That sounds more repetitive.

Because vatten is an ett-word in Swedish: ett vatten.

Adjectives often change form depending on the noun. With an ett-word in the singular, the adjective usually gets -t:

• en varm kopp
• ett varmt vatten → in practice just varmt vatten

So varmt agrees with vatten.

In Swedish, when you use a possessive like min, din, hans, hennes, vår, and so on, you normally do not also use the definite ending.

So:

• min termos = my thermos

not:

• min termosen

This is different from English, where you do not see a noun ending change, but the idea is similar: my thermos already identifies it, so Swedish does not also add the definite form.

It is an en-word:

• en termos
• min termos
• termosen

That is why the possessive is min, not mitt.

Compare:

• min termos because termos is an en-word
• mitt te because te is an ett-word

Ta med is a very common Swedish verb phrase meaning take along or bring.

So here:

• ta med te = bring tea / take tea along

You should learn ta med as a unit, not just ta by itself. On its own, ta usually means take.

This is a bit like English phrasal verbs, where a small extra word changes the meaning.

Because the two med do different jobs:

1. ta med = part of the verb phrase, meaning bring / take along
2. te med citron = tea with lemon

So in this sentence:

• first med belongs to the verb
• second med introduces what is added to the tea

Even though the same word appears twice, the grammar is different each time.

Because te is being used as a mass noun here, like tea in English.

Swedish often leaves out the article when talking about an uncountable substance in a general way:

• dricka kaffe
• köpa mjölk
• ta med te

If you were talking about a specific tea or a kind of tea, the wording could be different, but here plain te is natural.

Because med citron means with lemon in the sense of lemon as an ingredient or flavor, not with a whole lemon.

This is similar to English:

• tea with lemon
• not necessarily tea with a lemon

If you said med en citron, it would sound more like an actual whole lemon is involved.

Because till shows movement toward a destination:

• till jobbet = to work

But på jobbet shows location:

• på jobbet = at work

So:

• Jag tar med te till jobbet = I bring tea to work
• Jag dricker te på jobbet = I drink tea at work

This is a very important Swedish distinction.

Jobbet is the definite form of jobb, and here it refers to the speaker’s specific workplace: the job / work.

In Swedish, expressions like till jobbet are very common when talking about your usual workplace.

So even though English often just says to work, Swedish often uses the definite form:

• till jobbet

This is natural idiomatic Swedish.

Yes, you could, but the tone is a little different.

• till jobbet sounds very natural and everyday
• till arbetet is also correct, but often sounds a bit more formal or less conversational

In ordinary speech, many people would prefer jobbet here.

Yes, that is grammatically possible. You can change the order of the two infinitive phrases if you want to focus on a different action first.

But the original order feels logical because it presents the routine in a natural sequence:

1. pour hot water into the thermos
2. bring tea with lemon to work

So the original sentence sounds smooth and natural.

Hälla focuses on the action of pouring liquid.

• hälla vatten i termosen = pour water into the thermos

Fylla means fill, so it focuses more on the result:

• fylla termosen med varmt vatten = fill the thermos with hot water

Both can be correct, but they describe the action differently. In your sentence, hälla emphasizes the act of pouring, which is perfectly natural.
