The Daddy, I Want to Read books are very international in their use of the English language. However, since spellings and pronunciations of English words vary from one locale to another, it is necessary to have more than one version of these books. Three versions are currently available:
- Versio Americana
- Versio Britannica
- Versio Canadensis
The Commonwealth version (Versio Britannica) is intended for use in the UK and Commonwealth nations, except for Canada. This version uses the traditional English spellings of words, not the American spellings. It teaches the traditional British and Commonwealth pronunciations. This includes four different sounds for the letter A: short, long, middle, and broad. In contrast, the American version teaches only the short, long, and middle sounds, and does not label the middle sound. The Canadian Version (Versio Canadensis) is intended for use only in Canada. The spellings are unique to Canada.
