5. The fulfill / fulfil group (2)

In American spelling, when you add a suffix like -ing, -ed, or -er to a word, you double the final consonant only if the stress falls on the second syllable of the root word. Thus, as in British English, the verb 'pat-rol' gives 'patrolling' and 'patrolled'. On the other hand, the verb 'trav-el' becomes 'traveling', 'traveled', 'traveler' (GB 'travelling', 'travelled', 'traveller'). Some further examples: Click here to see the full text.
