I'm racking my brains here. Trying to find an answer, but no luck. What is the case usage with 'ile'? I always thought it was genitive plural, such as "Ile masz lat?" (with 'lat' being the gen-plural of 'rok'). So why does one say "Ile razy byłaś w Polsce?" and NOT "Ile razów byłaś w Polsce?". 'Razy' is nominative singular, yes? 'Razów' seems more logical to me, but I'm told it is wrong. Please help! Thank you so much!!!
