Context: I’m missing a cutting board. So I wrote in our telegram family group: “Wo ist eigentlich unser zweites großes Schneidebrett hin?” (literally: “Where is actually our second big cuttingboard thither?”).
By using the modal particle “eigentlich” I insinuate that something is oddly off and express an emotional state of curiousity and/or mild discontent.
By adding “hin”, I notify that I ask because it is not where it is supposed to be and not because I don’t know where it should be.
Now I ask myself, how would I express this additional information in English?
“Where has the second cutting board gone?”
This indicates that it’s not where it’s supposed to be, or at least not where you expected it to be and you’re looking for it. I can’t say for sure as I don’t speak German, but in English the “emotional state” you refer to is pretty clear in the context.
