I wrote "znalałam ją i cię" but it was wrong. Is there a rule to know when to use ciebie and when to use cię?
The grammar book says they come after prepositions, but this is not the case.
I think the position after "i" is accented, just like the beginning of the sentence. You use the "longer" version, but not the n- one.
Also my gut tells me you need longer version in the whole "her and me". (maybe it is all accented)
"Znalazłem ją i cię" it sounds very unnaturally. Definitely should be "... i ciebie". I am a native speaker.
