Native Hebrew speakers have a really hard time with words like "squirrel," which they pronounce "skvirl." A lot of difficulty with the "w" sound in general, but especially in combination with other consonants.
I have an unreasonable love for the way native Hebrew speakers speak English. It reminds me of my college boyfriends mothers and its just incredibly endearing. I kind of want to hug someone when I hear it.
I speak English, German (grew up in Austria and then lived, studied and worked in Germany and Austria as an adult) and French (got a French law degree there). I would really like to have Leela learn both languages, because really learning languages has been one of my great joys.
We met a little boy today who spoke English, Hindi and Spanish at 2 and I was so impressed.
