Questions & Answers about Я хочу, чтобы мы сделали ещё один дубль.
Why is the past tense verb сделали used here when the translation says "to do"?
This is the main rule for expressing indirect wishes in Russian! When you want someone else to do something, you use хотеть (to want) + чтобы (so that) + the past tense of the verb. Even though the action hasn't happened yet, the word чтобы forces the following verb into its past tense form.
Why do we use the perfective verb сделали instead of the imperfective делали?
The speaker wants to successfully complete exactly one more take. Perfective verbs like сделать are used when you want to focus on the result and completion of a single action, rather than an ongoing or repeated process.
How does ещё один translate to "one more"?
The word ещё usually translates to "still" or "yet". However, when placed before a number, it means "more". Therefore, ещё один literally translates to "still one", which is the standard Russian way to say "one more" or "another".
What case is дубль in here, and why hasn't its ending changed?
It is in the accusative case because it is the direct object of the action (the thing being made). Because дубль (a take) is a masculine inanimate noun, its accusative form is identical to its dictionary (nominative) form.
