The Japanese word for "Milk Cow" is chichiushi 乳牛.
- A semordnilap is when you write a word backwards and get a different word. For example, nyuugyuu 乳牛, "Milk Cow," written backwards is gyuunyuu 牛乳, "Cow Milk."
Beware: some kanji that are difficult to handwrite are easy to type on the computer, which may skew the usage statistics.
