Looking At American Spelling
Marion Field was Head of English in a large Comprehensive School for many years and is an examiner for GCSE English. She is the author of several language improvement books for writers.
American spelling differs from English spelling in a variety of ways. Frequently, nowadays, the American spelling is also given in English dictionaries and in some cases both spellings are now acceptable.
DOUBLING CONSONANTS - OR NOT
Before a suffix is added, the consonant is often not doubled.
Dropping the ‘I’ and the ‘p’
Look at the following examples. The ‘i’ and the ‘p’ are not doubled as they would be in English spelling.

The following root word appears in English dictionaries both with a single T and a double one although the usual English spelling is with a double T. However, when the suffix ‘-ment’ is added, the Americans use a double T while the English use only one.
