"The moose drink water."
Translation:Älgarna dricker vatten.
No, we don't have words for female vs male moose. There are a few old word pairs like that, but I can't really think of any that are in common use anymore. The genders in Swedish are common gender (en words) and neuter (ett words).
PS I mean there are words for female and male moose, but they're älgko 'moose cow' and älgtjur 'moose bull' respectively. The calf is älgkalv.
