Questions & Answers about В этой программе много деталей.
Why does the word деталь change to деталей here?
Because of the word много (many). After quantity words like сколько, много, and мало, we must use the Genitive plural case for things we can count. Деталь is a feminine noun ending in a soft sign, so its Genitive plural ending is -ей.
Why do we say в этой программе instead of в эта программа?
We use the Prepositional case here because the sentence describes a location (where the details are). The preposition в (in) forces the dictionary form эта программа (this program) to change its endings to этой программе.
There is no verb in this sentence. How does Russian say 'There are'?
Russian doesn't have a direct equivalent for 'there is' or 'there are' that it uses all the time. Instead, sentences often just state the location and the subject. Literally, this translates as 'In this program [are] a lot of details,' with the present-tense verb 'to be' completely skipped.
I've seen деталь used for machine parts. Does it also mean 'detail' like information?
Yes! Деталь is a versatile word. It can mean a physical component or part of a machine, but it also perfectly translates to a piece of information or a 'detail' in a plan, software program, or story.
