Wikipedia has a lot of occurrences for the word "civillians", such as:
At least 35 civillians were killed at the incident
I began fixing them to "civilians", but then had a doubt. Is "civillians" actually correct?
At least one dictionary has the term with two "l": http://www.thefreedictionary.com/Civillian but if I understand well it is listed as "Middle English". Is this an old word that should not be used in a modern encyclopedia?
