I downloaded a Russian vocab flashcard app recently (Russian Words, by sensus lingua) and have run into a confusing issue with it. Everything looked legit enough (to my A1 level eyes, haha), and there seemed to be a good deal of overlap with the basic words I had already learned elsewhere... but then! As one of the cards contained an error (the flipside, which was supposed to contain the same Russian word as the front + its translation, showed a different Russian word instead) I googled both words to resolve my confusion, only to find that neither of them appear to be existing words! Google Translate didn't understand either one, Google proper found only 6 results for one and 200 for the other, and google.ru autochanged both of them into other words.
The words (or "words") in question are безудобный and безкрасочный, one or both of which according to my app should mean "colourless". Does anyone know what might be going on here? They sure look like Russian adjectives to me, but apparently they aren't. Is this just a different Slavic language? If this app has been lying to me I'd better start double checking everything I've learned so far!
Thanks very much in advance for any clarification you guys can give me! <3
Edit - mystery solved! My app was lying, or at least it doesn't have any more of a clue about prefixes than I do. Boo! Thanks so much to everyone who commented! :)
