Grammar Rule Behind the Two Spellings
The difference comes from spelling conventions rather than grammar.
American English
American English often simplifies spellings by avoiding an extra l in many derived words.
Examples include:
- cancel → cancelable
- travel → traveling
- model → modeling
British English
British English commonly doubles the l before adding certain suffixes.
Examples include:
- cancel → cancellable
- travel → travelling
