emigrate
To leave your country to live in another one permanently.
To emigrate means to leave your home country permanently to live in another country. When people emigrate, they pack up their lives and move to a new nation to build their future there, unlike taking a vacation or studying abroad temporarily.
When someone's great-grandparents emigrated from their homeland, they left familiar places behind to start fresh somewhere new. Emigrating is one of the biggest decisions a person can make, since it can mean leaving behind familiar places, friends, and often family members.
Notice that we say someone emigrates from a country. The word focuses on the departure, the leaving behind. When we want to emphasize where someone went instead, we use a related word: immigrate. So a person might emigrate from Poland but immigrate to Canada. Same journey, different perspective.
People emigrate for many reasons: better job opportunities, education, safety, or to join family members who left earlier. Throughout history, millions have emigrated to pursue dreams of freedom and prosperity. The journey requires courage, since emigrants must adapt to new languages, customs, and ways of life in their adopted countries.
