Questions & Answers about Мы заботимся о нашей свекрови.
Why doesn't свекровь add the -ер- suffix in the prepositional case like мать does?
Although свекровь (husband's mother) ends in a soft sign just like мать, it is a standard 3rd declension feminine noun. Only the irregular nouns мать and дочь add the special -ер- stem in their oblique cases (becoming матери and дочери). For свекровь, you simply change the soft sign to -и to get свекрови.
Why do we use the prepositional case (о нашей свекрови) here?
The verb заботиться (to care for, to look after) requires the preposition о (or об before a vowel) plus the prepositional case to indicate who or what is being cared for.
Does свекровь mean any mother-in-law?
No, Russian is very specific about in-laws! Свекровь is strictly a husband's mother. If you are talking about a wife's mother, you must use the word тёща.
Why does the verb заботимся end in -ся?
