Hon glömde att bifoga filen, så jag bad henne vidarebefordra mejlet igen.

They are both in the simple past.

• glömde = past tense of glömma = to forget
• bad = past tense of be = to ask / request

So the sentence is telling a completed past event.

A useful note: be is an irregular verb:

• be
• ber
• bad
• bett

That often surprises English speakers, because bad looks like the English adjective bad, but in Swedish it is just a verb form.

After glömma followed by another verb, Swedish normally uses att + infinitive:

• glömma att göra något = to forget to do something

So:

• glömde att bifoga = forgot to attach

This is very similar to English forgot to attach. In Swedish, the att is the normal marker here.

Because be någon göra något uses a bare infinitive in Swedish.

Pattern:

• jag bad henne vidarebefordra mejlet
• literally: I asked her forward the email

So even though English says asked her to forward, Swedish does not normally use att after be in this structure.

Compare:

• Hon glömde att bifoga filen.
• Jag bad henne vidarebefordra mejlet.

So one verb pattern requires att, and the other does not.

Because henne is the object form of hon.

• hon = she → subject form
• henne = her → object form

In this sentence, she is the person being asked:

• jag bad henne = I asked her

So Swedish works like English here:

• she asked → subject
• I asked her → object

Because Swedish usually adds the definite article as an ending.

• en fil = a file

• filen = the file

• ett mejl = an email
• mejlet = the email

This also shows grammatical gender:

• fil is a common-gender word: en fil → filen
• mejl is a neuter word: ett mejl → mejlet

So English uses a separate word the, but Swedish often adds definiteness at the end of the noun.

Yes. bifoga is a standard and very common verb in formal and everyday Swedish for attach, especially in email or document contexts.

Examples:

• Jag bifogar filen. = I am attaching the file.
• Se bifogad fil. = See attached file.

Related noun:

• bilaga = attachment / enclosure

So glömde att bifoga filen is very natural Swedish.

It means to forward or pass on, especially for messages and emails.

It is a compound verb:

• vidare = onward / further
• befordra = convey / forward / transmit

So:

• vidarebefordra mejlet = forward the email

This is a normal verb for email contexts. English speakers often notice that Swedish likes long compound words and compound verbs like this.

Here så means so and links the two parts of the sentence:

• Hon glömde att bifoga filen, så jag bad henne...
• She forgot to attach the file, so I asked her...

It shows a result or consequence.

So the logic is:

1. she forgot the attachment
2. as a result, I asked her to forward the email again

Because the sentence has two full main clauses:

• Hon glömde att bifoga filen
• så jag bad henne vidarebefordra mejlet igen

A comma before så is very common when it links two independent clauses. It helps readability.

You may see slightly different punctuation styles, but in a sentence like this, the comma is completely normal.

Because så here is a coordinating conjunction, not a fronted adverb inside the clause.

That means the second part keeps normal main-clause word order:

• jag bad henne

Swedish main clauses follow the V2 principle, but since jag is the first element in that clause, the verb naturally comes second:

• jag bad

English speakers sometimes expect inversion after any word at the beginning, but that is not what is happening here.

A useful distinction:

• ..., så jag bad henne... = ..., so I asked her...
• Så bad jag henne... could exist in another context, where så means something more like then/so, but that is a different structure.

Here igen means again, and it applies to vidarebefordra mejlet.

So the idea is:

• I asked her to forward the email again

It does not naturally mean that she forgot again.

If you wanted to say she forgot again, you would place igen earlier:

• Hon glömde igen att bifoga filen.

Word placement matters a lot here.

No, not in this structure.

glömde att + infinitive means forgot to do something.

So:

• glömde att bifoga filen = forgot to attach the file

If you want forgot that..., Swedish uses a full clause instead:

• Hon glömde att hon hade bifogat filen.
• She forgot that she had attached the file.

So this is an important difference:

• att + infinitive = forgot to do
• att + clause = forgot that...
