"Cop-uh-kol-uh."
'Une copine' translates to 'a girlfriend' in English.
Une copine may be either a female buddy or a girlfriend. This is to be deduced from context.
The Cajun French translation for "girlfriend" is "p'tite amie" or "copine."
Depends of the context. "Ami" is masculine (the feminine is "amie") and "copine" is feminine (the masculine is "copain"). Both mean "friend", but "ami" means a better friend than "copain". Often, "copain" is used for "petit copain" or "copine" for "petite copine", and then that mean "boyfriend" or "girlfriend".
