What does halloja mean in swedish?

Answer 1

It means "hello". Mind though that it is not used as the standard greeting phrase, but is instead used in expected scenarios, such as in a phone call where you often know who the other part is. Contained within the phrase is an underlying rule of the answerer adding the "ja" to the "hallo/hallå", as if he/she has already talked to the person before. A comparison might be "hello you".
