Fulfill is the American spelling of the verb meaning to accomplish or to satisfy. Fulfil is the preferred spelling outside North America. Both forms are common in Canadian writing.

The spelling preferences extend to fulfilment and fulfillment, but not to fulfilled, fulfilling, and fulfiller, which have two l’s everywhere.
