I won’t try to find an equivalent to all these in English language but I think many of these expressions are very close to the Swedish ones. Your homework will be to translate these because the list is long. Here is some help because my colleague already made a post like this earlier with idiomatic translations. So you guys can compare it with how Swedes think about attributes and characteristics compared to English speakers.
