In this weekly post, we bring more useful content from the Macmillan Dictionary to English language learners. These tips are based on areas of English (e.g. spelling, grammar, collocation, synonyms, etc) which learners often find difficult. Here is some advice about spelling the verb fulfil:
The verb fulfil has only one ‘l’ in the middle (unlike the adjective full, which has a double ‘l’).
✗ Life is too short to enable man to
fullfil his dreams.
✓ Life is too short to enable man to fulfil his dreams.
Note that in British English, there is one ‘l’ at the end of the verb: fulfil
In American English, there are two ‘l’s at the end: fulfill
In both British and American English, the final ‘l’ is doubled in the forms fulfilled and fulfilling:
✗ a duty that must be
✓ a duty that must be fulfilled
