Questions & Answers about Вы должны напомнить об этом вашей любимой жене.
Why does the sentence use вашей любимой жене?
The verb напомнить (to remind) requires the dative case for the person you are reminding. Since жена (wife) is feminine, we use the feminine dative endings for the whole phrase: the possessive pronoun ваша becomes вашей, the adjective любимая becomes любимой, and the noun жена becomes жене.
Why is it об этом and not just о этом?
The preposition о (about) changes to об when the next word starts with a pronounced vowel (like the э in этом). This makes it easier to say. Also, этом is in the prepositional case, because the preposition о/об always requires the prepositional case when talking about a topic.
Why does должны end in -ы?
The word должны (must / obligated) is actually a short adjective, so it has to match the subject of the sentence. Because the subject here is Вы (formal or plural 'you'), we must use the plural ending -ы. This applies even if you are speaking formally to just one person.
Why use the perfective verb напомнить instead of the imperfective напоминать?
