These days you just Google and it will cross reference common misspellings and typos.

Just Googled "nife" and got some images of "knives", but other hits were actually for "nife"

Whomever thought that initial silent consonants were a good idea, never anticipated the concept of the dictionary. How do I look up what numonia is, when I can't find it in the N-section?

Yeah, it's Greek to me.
