Questions & Answers about На форумах мы обсуждаем посты о разных мнениях и социальных темах.
Why does мнениях end in -ях but форумах and темах end in -ах?
Both are in the prepositional plural, but the ending depends on whether the original word is "hard" or "soft." Форум (forum) and тема (topic) end in hard consonants, so they take -ах. Мнение (opinion) ends in a soft vowel sound (-е), so it takes the soft ending -ях.
Why do the adjectives разных and социальных end in -ых?
These adjectives are modifying nouns in the prepositional plural (о мнениях, о темах), so they must match that case and number. For most adjectives, the prepositional plural ending is -ых (or -их if the stem ends in a spelling rule letter like к, г, х, ш, щ, ж, ч or is naturally soft). Here, разный and социальный have hard stems, so they take -ых.
Why do we use на for форумах instead of в?
In Russian, the internet and digital spaces usually take the preposition на (on/at) rather than в (in). Just like you say на сайте (on the website), you say на форумах (on forums).
What case is посты and why didn't it change?
It is in the accusative case because it is the direct object of the verb обсуждаем (we discuss). Because пост is an inanimate masculine noun (not a living thing), its accusative plural looks exactly the same as its nominative plural (the basic dictionary plural).
Do we only have to write о once for both мнениях and темах?
Yes! Because разных мнениях and социальных темах are joined by и (and) and are part of the same list governed by "about," you only need to use the preposition о once at the beginning.
