  Historically, they are interchangeable. Insure has come to mean primarily insurance, particularly in the UK, though the first definition given in the OED is still "to make a person sure of a thing" (marked obsolete), but I still see insure with that meaning regularly from Americans. I like this quote: http://www.wsu.edu/~brians/errors/assure.html http://www.wsu.edu/~brians/errors/assure.html "Other authorities, however, consider “ensure” and “insure” interchangeable. To please conservatives, make the distinction." Looks like the Grammar Nazis have won, when we're giving writing advice intended purely to avoid their wrath. OED ref, though I don't think that's a public link if you're not on a campus with a licence: http://dictionary.oed.com/cgi/entry/50118480?single=1&query_type=word&queryword=insure&first=1&max_to_show=10 http://dictionary.oed.com/cgi/entry/50118480?single=1&qu...

    It's not being a grammar nazi to point out that something is not misspelled.
