I purchased the reword app and have found some odd translations. Particularly, 연화, which is being translated as "soft currency." Google translate translates it as softening, a google image search result shows some anime, and Wiktionary has no results.
Is this legit? Is it a trendy current word or like an out of date translation?
They are both legit, but 연화 "soft currency" is quite a rare term (unless you are an economist, I guess) - if you say 연화 without context, people will most likely assume "softening" or a personal name.
Even 연화 softening sounds like a technical term describing some kind of industrial process. For everyday usage, people will use verbs like 무르다/물러지다/부드러워지다/etc. If you are a beginner, you don't really need to learn 연화 right now.
