Avast me hearties! This here be the 10th annual Talk Like A Pirate Day, and if you don't join in we'll make you walk the plank!
Er, so our pirate vocabulary is somewhat thin, making this the perfect opportunity to brush up on high seas jargon.

While the basics - Ahoy! Avast! Aye!, Aye aye! and Arrr! - are pretty easy to master, the founders of International Talk Like A Pirate Day have compiled a handy "how to" guide (with French, Dutch and German translations).
Just remember to always observe these simple rules:
Double up on all your adjectives and you'll be bountifully bombastic with your phrasing. Pirates never speak of "a big ship", they call it a "great, grand ship!" They never say never, they say "No nay ne'er!"
Drop all your "g"'s when you speak and you'll get words like "rowin'", "sailin'" and "fightin'". Dropping all of your "v"'s will get you words like "ne'er", "e'er" and "o'er".
Instead of saying "I am", sailors say, "I be". Instead of saying "You are", sailors say, "You be". Instead of saying, "They are", sailors say, "They be". Ne'er speak in anythin' but the present tense!
So, brush up on your skills, for as Cap'n Slappy exclusively told The Huffington Post UK: "We love our mates in the UK!
"Keep spreadin' the word - and the word be, 'ARRR!'"
