I’m only level 11, but this has been happening a lot for me recently.
I was talking to a friend the other day, and he said something along the lines of
I haven’t seen 低下 before, but I understood the general meaning from the context and from knowing what the two kanji meant. I even knew how to pronounce it!
I was reading an article on the differences between Redux and MobX (programming stuff), when, for some reason, I decided to look up an article about it in Japanese to see what it looked like. Much to my surprise, I was already familiar with a lot of the words. The coolest thing, however, was seeing a word I hadn’t seen before and being able to guess the meaning exactly, before looking it up to confirm.
At level 10 or so we learn 開発. I came across 開発者 on the page and just about jumped with glee when I was able to guess the meaning.
On a semi-similar note, when I saw the word 共通点, I wasn’t able to determine what it meant (though once I looked it up it makes sense), but I was able to pronounce the word, which makes looking it up so much easier than searching by components. Haha.
I guess I’m just gushing that I love this web app. What an awesome tool for studying Japanese.
