Compound words, particularly compound nouns, are common in Swedish. Swedish is more likely to have a compound noun where English might use a compound, a hyphen, or two separate words, for example vattenskyddsområde (water protection area). But of course, it’s not that simple: for example järnväg (railway) is a compound in both languages, but English is reluctant to extend the exercise: järnvägslinje (railway line).
Back to last week’s question: Norstedts lists the following: lögndetektor (lie detector), mindetektor (mine detector), and rökdetektor (smoke detector). But dold detektor means hidden detector. So I guess if we want to look for rules, we might say that the compound noun, made up of first element (FE) + second element (SE), is a specific type of SE, whereas separate words are used for a description of a general SE.
The following example works equally well in Swedish and English: blåbär (blueberries) are a specific type of berry, whereas blå bär (blue berries) are any old berries that happen to be blue.
That simple rule won’t cover everything, and a lot seems to me to depend on the differences between the ways adjectives work in Swedish and English. Contrast:
en kort hårig flicka = a short, hairy girl
en korthårig flicka = a short-haired girl
rök fritt = smoke freely (smoking allowed)
rökfritt = smoke-free (smoking prohibited)
There is a phenomenon in Swedish called särskrivning (separated writing), which refers to the incorrect use of separate words where a compound is correct. If you want to see the kind of fervor this stirs up, have a look at skrivihop.nu. While the “short-haired girl” example above provides a nice example of how linguistic functions are realised differently in English and Swedish, I do find it hard to take seriously the argument that särskrivning would result in any serious misunderstandings. But they do offer this helpful piece of advice:
Om det uttalas som ett sammansatt ord skall det också skrivas som ett sammansatt ord!
If it is pronounced as a compound word, it is also written as a compound word!
Yeah, right.
