After five and a half years of speaking French to my son and my nephew, I feel very comfortable in my non-native language.
Until last week, when I was playing with my six-month-old niece, bouncing her on my lap and reciting comptines and singing and enjoying her humongous grins. "Oh, que tu es mignon!" I exclaimed. [You are soooo cute!]
And then I heard myself: I was using the masculine adjective ending instead of the feminine form (mignonne) with this baby girl! Five and a half years of speaking French to little boys means that the masculine adjective endings are the ones that will automatically jump into my head when I'm talking to a child--but in five weeks or so I'm going to have a petite fille around the house! Not only will I need to get used to having a new baby to take care of, I'll need to reconfigure my French grammar paradigm to include girls, won't I?
