Questions & Answers about دستیار من قطعه را نگه میدارد، در حالی که من همزمان آن را میبرم.
The lesson mentions using the Present Continuous with در حالی که. Why does this sentence use the simple Present Indicative (نگه میدارد and میبرم) instead?
While the Present Continuous is often used for simultaneous actions, the simple Present Indicative in Farsi is very flexible and can easily represent ongoing actions. Because در حالی که (while) and همزمان (simultaneously) already make it completely clear that the actions are happening at the exact same time, adding the continuous auxiliary verb isn't strictly necessary here.
How is the verb نگه میدارد formed?
It comes from the compound verb نگه داشتن (to keep or to hold). نگه is the non-verbal part, and داشتن (to have) is the verb. Notice that the present tense prefix می attaches directly to the verb part, making it نگه میدارد (he/she holds).
Do we really need the word همزمان (simultaneously) if we already have در حالی که (while)?
Grammatically, no. در حالی که already establishes that the actions are happening alongside each other. Adding همزمان just gives extra emphasis to the exact simultaneous nature of holding and cutting the piece, which is very natural when describing a careful physical process.
Why is the object marker را used twice in this sentence?
