How many books have you read that contained words that originated with sailors? Probably as many as the number or characters that had a past related to the sea. There are entire series dedicated to men in uniform, so many readers have encountered one. But use of the words that came from the sea aren't necessarily restricted to romance writers. A term might creep into the ships that sail amongst the stars. And don't forget ships that transverse the oceans of fantasy worlds.
In honor of Fleet Week, a tip to writers. A word or two (don't use the entire dictionary) can add a hint of authenticity to a work.The U.S. Navy has compiled multiple glossaries of naval slang that has worked its way into common English. Whether you want to bamboozle or use "know the ropes" in its original meaning (which wasn't complimentary), check out naval slang.
