  • Hi digik! If you put fulfill and fulfil into the Google Ngram Viewer ( you'll see that over time, the double-ll version has overtaken the single-l version.

    If you toggle the corpus from English to American English or British English, you'll see that fulfil seems to be chiefly British, and fulfill is American, and that the American spelling is seen more commonly overall. But if I was writing a paper for a class in England and I saw the red spellcheck squiggly line come up, I'd ask a local.
