Glossary

Did you know that half the stuff you say has salty sea legs? When you 'test the waters,' you’re practically a sailor. And when things go 'off the deep end,' well, you might as well grab a life jacket. 'Loose cannon'? Nautical. 'By and large'? Also nautical. Even 'shipshape' is—you guessed it—nautical. We’ve been talking like sailors since forever, but most of us don’t even know we’re doing it. It’s time to own your inner seafarer! Let us help you navigate these maritime phrases so you can drop them into conversations with the precision of a seasoned captain. Anchors aweigh, linguists!
