Irregular English

Yesterday Sven found out about the irregularities of English. He pointed to a picture of 9 geese and said they were "gooses". I had to tell him that it is one goose, but many geese. At first, he tried to argue with me that it was "gooses". But when I wouldn't give up, he said it to himself a few times, as if to reinforce the lesson, then smiled. Perhaps he thinks the English language is a little bit silly.

Update: Sven is struggling this week with "Woman" and" Women." He wants to say "Womans" and I corrected him, but he doesn't hear the difference, so he looks confused.
