Fine, if we are talking about the house, we could also talk about the Swedish words for thing:
Swedish for a thing is en sak.
Attention now! Why is a house - ett hus, but our second word for a thing - en sak. Well, that’s because the word hus is of the neuter gender and the word sak is of non-neuter, that is, masculine or feminine (feminine in this case) gender. You see, all words (or rather nouns) are of one of three genders in Swedish: masculine, feminine or neuter. You can tell their gender by the article they have. For example, ett hus has the article ett (which usually gets shortened to et in other forms) in front of it, and that means it’s neuter, while en sak has an articleen in front of it, so it’s not neuter.
So words can be either: one, neuter if their article is ett or two, non-neuter* (either masculine or feminine, but that doesn’t really matter for our practical purposes) if the article is en.
We won’t bother with genders and will just call the first group ett-words, and the second group en-words.
