Gregory's ServerOne fun thing is that the Romanian word for "she" - "ea" - is the same as the Latin word for "she" - "ea". But, even though Romanian is descended from Latin, the Romanian "ea" is not descended from the Latin "ea"!
Another thing is that the neighbouring languages Irish and English have the exact same word for "she" - that is, it's pronounced exactly the same, although written differently - but the two words are not at all related. Apparently.
In a similar vein, Finnish "hän" obviously looks a lot like Swedish and Norwegian "han", but again, this is a complete coincidence. Although, apparently, the origins of Old Norse "hann" are not entirely certain.
