English is the official language for the crew on board but perhaps not in the country they come from. Improving the English language or learning a new one is something you see very often among the crew activities.
Crew members can find computers and software dedicate to language learning in the ship. They can go in their free time to study, but the experts’ advice is to get a boyfriend/girlfriend who speaks the language you want to learn. It is said this method is better than any software.
The roommate is also a good option, but a love partner is the fastest way to learn and improve. Just make sure they speak the language you want to learn, fluently. You won’t even notice but every moment with your partner speaking the language you want to learn, is a valuable lesson.
“In no time you will find yourself speaking and sometimes, snoring in a new language” That what the experts say.
