Learn Farsi: این عمل به وصول بدهی کمک کرد. - This act helped with the collection of the debt.

In Farsi, the compound verb کمک کردن requires the preposition به to introduce the thing or person receiving the help. While English uses "helped with" or "helped to" depending on the context, Farsi consistently links the helper and the helped action or entity using به.

وصول is translated as "collection" here. Is this an infinitive?

It is an Arabic-derived verbal noun, meaning "receipt" or "collection." At the B2 level, you will frequently see these verbal nouns used in formal, business, or legal contexts instead of native Farsi infinitives (like گرفتن). It connects to its object (بدهی) using an ezafe: وصولِ بدهی.

How does this sentence connect to the action focus constructions like اقدام به that we are studying?

While this sentence uses کمک کردن به rather than اقدام به, it shares the exact same grammatical mechanism for focusing on an action. Instead of using a clunky subordinate clause with a conjugated verb (e.g., "helped so that they could collect the debt"), it uses به followed directly by an action noun (وصول). This makes the sentence concise and emphasizes the abstract action itself.

How is the word بدهی (debt) formed grammatically?

It is built from بده, which is the imperative form of دادن (to give). Adding the noun-forming suffix ـی creates بدهی, which literally translates to "that which must be given" (a debt). You might recognize the same root in (debtor).
