Questions & Answers about Я не хочу принимать ни твои условия, ни его.
Why is there a negative word before the verb if we are already using "neither ... nor"?
Russian requires double negation. Whenever you use the double conjunction ни ... ни (neither ... nor), the main verb of the sentence must also be negated with не. You are literally saying "I do not want to accept neither your conditions, nor his."
Is the comma before the second ни mandatory?
Yes. When using repeating coordinating conjunctions like ни ... ни, и ... и, or или ... или, Russian punctuation rules require you to always place a comma before the second part of the conjunction.
Why use the imperfective verb принимать instead of the perfective принять?
When you express a strong refusal or general unwillingness to do something using не хочу (I don't want), Russian almost always follows it with an imperfective verb. It emphasizes rejecting the idea of the action entirely, rather than just failing to complete one specific instance of it.
At the end of the sentence, why doesn't его change form to match the plural noun it replaces?
Unlike твои (your), which changes to match the plural noun условия (conditions), the third-person possessive pronouns его (his), её (hers), and их (theirs) are frozen forms. They never change their endings, regardless of the gender, number, or case of the noun they describe or stand in for.
