What is the difference between שניה and שנייה?
It's the same word: with nikkud you only write with one yud: שְׁנִיָּה. Without nikkud you would usually write with two, שנייה, but the rules for writing without nikkud aren't as strict.
I wrote שנייה and it told me "almost correct" and changed it to שניה even though there is no nikkud in this question :(
One second, I am putting on a shirt.
