IPA: /ˈɡɜːrˌlfrɛnd/
KK: /ˈɡɪrˌlfrɛnd/
A woman with whom someone has a romantic or affectionate relationship.
She introduced her boyfriend to her girlfriend at the party.
Girlfriend → It is formed from "girl" (from Old English *gyrela*, meaning a young woman or female child) and "friend" (from Old English *freond*, meaning a person who loves or is fond of another). The word "girlfriend" refers to a female friend, particularly one with whom one has a romantic relationship.
Think of a 'girl' as a young woman and a 'friend' as someone you love or are fond of. This helps you remember that a girlfriend is a young woman who is also a friend.
