Learn Swedish: Vi funderar på varför pengarna egentligen saknas. - We are thinking about why the money is actually missing.

Because varför pengarna egentligen saknas is an indirect question, which acts as a subordinate clause. In Swedish subordinate clauses, sentence adverbs like egentligen (actually) or inte (not) must come before the verb. If this were a direct question, the verb would come earlier: Varför saknas pengarna egentligen?

Why is pengarna in the plural form? In English, "money" is singular.

In Swedish, the word for money (pengar) is almost always treated as a plural noun. To say "the money", you must use the definite plural form pengarna.

Why does the verb saknas end with an "s"?

Saknas is an s-verb. While it comes from the active verb att sakna (to miss or lack), adding the "s" to the end gives it a passive meaning. It is the standard way to say "is missing" or "is lacking" in Swedish.

Why do we use the preposition på after funderar?

The verb att fundera (to think, to ponder) is usually paired with the preposition på to mean "think about" or "wonder about". Prepositions rarely match up perfectly between English and Swedish, so it is best to memorize funderar på as a set phrase.
