Jackspeak of the Royal Canadian Navy
Jackspeak: Certain words or terminology that are commonly used in the Canadian Navy.
The Canadian Navy has it's own terminology and slang that is still evolving to this day. Much of the language used is still derived from the Royal Navy, although as Canadians many local customs and slang have come about.
This list was compiled over the years and was finally published in 2014 as "Jackspeak of the Royal Canadian Navy (2015 edition)" In 2018, a completely revised 2nd edition will be released. The 2018 edition features expanded and revised definitions, many more example sentences, and over 400 new terms.
