Questions & Answers about Когда-то у неё была тайна.
What does -то add to когда in this sentence?
The suffix -то adds a sense of "some" or "unknown" to question words. Since когда means "when", adding -то makes когда-то, which means "at some time" or "once" in the past. It shows that the exact time isn't known or doesn't matter.
Why is there an "н" in неё? Shouldn't "she" in the genitive case just be её?
When pronouns starting with a vowel (like он, она, оно, or они) come directly after a preposition like у, an н is added to the beginning to make it easier to say. So, instead of the awkward-sounding у её, we say у неё.
Why is the verb была in the feminine form if "she" is already feminine?
In Russian, to say someone "had" something, you literally say "by them was [the thing]". The grammatical subject of the sentence is actually the thing being possessed, not the person. Here, the possessed thing is тайна (a secret). Since тайна is a feminine noun ending in -а, the past tense verb must match it, becoming была.
Could I say У неё когда-то была тайна instead?
Yes, you can! Russian word order is very flexible. Putting когда-то at the very beginning of the sentence just emphasizes the time aspect, setting the scene like a story: "Once upon a time..." or "At one point in the past...".
