בדקנו את המקור.

בדקנו is a past-tense verb meaning we checked or we examined.

It comes from the verb בדק, meaning to check / examine / inspect.
The ending ־נו marks first person plural in the past tense, so the whole word means we checked.

Hebrew often leaves out subject pronouns when the verb already makes the subject clear.

In בדקנו, the ending ־נו already tells you the subject is we, so אנחנו is unnecessary.

You could say אנחנו בדקנו את המקור, but that would usually add emphasis, like we checked the source.

את is the direct object marker. It has no real English translation.

It is used before a definite direct object, meaning a specific thing being acted on.

So in בדקנו את המקור:

• בדקנו = we checked
• את המקור = the source / the original

A good way to think of את is: it tells you that המקור is the thing that was checked.

Because את normally comes before a definite direct object, and המקור means the source or the original.

The ה־ at the beginning is the Hebrew definite article, equivalent to the.

So:

• מקור = a source / source
• המקור = the source

Since the sentence refers to a specific source, המקור is the natural form.

המקור most commonly means the source.

Depending on context, מקור can also mean:

• origin
• original
• source text
• source of information

So this sentence could mean We checked the source, but in some contexts it might also be understood as We checked the original.

The root is ב־ד־ק.

This root is connected with meanings like:

• checking
• examining
• inspecting
• testing

The basic dictionary form is usually לבדוק = to check.

So:

• root: ב־ד־ק
• past he checked: בדק
• past we checked: בדקנו

It is pronounced approximately:

badaknu et hamakor

A slightly more careful breakdown:

• בדקנו = ba-DAK-nu
• את = et
• המקור = ha-ma-KOR

The strongest stress is usually on:

• DAK in בדקנו
• KOR in המקור

With ניקוד, it would usually be written:

בָּדַקְנוּ אֶת הַמָּקוֹר

This can help a learner see the pronunciation more clearly, but in everyday Modern Hebrew, it is normally written without vowels:

בדקנו את המקור

The neutral, natural order here is exactly what you see:

בדקנו את המקור

Hebrew word order is somewhat flexible, though. You might also see:

• אנחנו בדקנו את המקור = We checked the source
• את המקור בדקנו = It was the source that we checked

These alternatives change the emphasis, but the basic meaning stays similar.

Yes. The verb בדק is fairly broad.

Depending on context, בדקנו could mean:

• we checked
• we examined
• we inspected
• we tested

In this sentence, we checked is usually the most neutral translation, but context may make another English verb sound more natural.
