As any linguist (and anyone who knows unrelated languages, probably), not all languages express things the same way. Worse yet, its not possible to express everything logically, so all languages are forced to rely on something arbitrary to express certain concepts.
I try to find out how other languages do things, but I rarely meet with any success. Most dictionaries I find online assume you already know the language, which of course makes sample sentences useless.
It seems like the only way to find out how a language does anything is to know it. This means that as a conlanger, its nigh impossible to make a conlang that doesn't in some way resemble the languages you know. This can obviously be quite a problem if you're monolingual, as most Americans are. I'm not monolingual, but even I have a problem avoiding Euro-centrism since the only other language I know well is German. Yeah, German does some things differently, but its not that different from English since the two are closely related. They tend to overlap more often than not.
Is there any convenient way to get information on specific things in languages without just having to learn half a dozen unrelated languages?
