noun
mother country
A loanword from English, used to refer to one's homeland or native country, often with a nostalgic or formal nuance. Not as common as native terms like 祖国 or 母国.
彼は長年海外で暮らした後、マザーカントリーに戻ることを決意した。
After living abroad for many years, he decided to return to his mother country.
Borrowed from English 'mother country', a compound of 'mother' and 'country'. The Japanese form is a direct phonetic adaptation.
