I had analyzed 食道静脈瘤破裂 here; but didn’t knew that 静脈瘤 is actually 静脈+瘤; bumped vein, indeed that makes a lot of sense.
I’m surprised at 食道 being the least common; as it was the only one I could understand/guess the most easily.
the “but” が can come after an i-adjective as well.
Oh, yes. Actually I think of them both (動詞 and 形容詞) as a same category… is there a word for them both ?
