Yeah I don’t really pay attention to language much so I’m not an expert whatsoever but I do pay attention to inconvenience. There is obviously scientific expressions to distinguish but everyday casual conversation shouldn’t be so technical I think. Arabic and Somali have a single word to describe maternal aunt but imagine saying maternal aunt to a random person in a random conversation, I really want to try and avoid being pretentious as much as I can lol
The word “family” to me was always interesting because it’s ALWAYS contentious. You could use scientific definitions but everyday casual conversations don’t work like that. People will always say things like family is the most important thing, but that means different for everybody. Some will go as far as include the tribe, some aunts and uncles, some extended members etc. You also have the mother vs wife thing. Now that I’m thinking about it, Arabic and Somali languages have a way of distinguishing between them but English is just way too broad. Even in legal documents, you have the assumption that your family is your wife and children.
