No way to read '+' in the four classics.

[skripp]

In the four classics, there are '+' signs after certain words / expressions. But there is no way to get the definition. Tried on both Android and iOS.

In GCR there are a lot of words colored blue, but only a few have a '+' sign, is this normal? If there's a '+' sign then you can touch it and get the definition by the author.

Yes, the ones in those are not linked but merely suggesting you look at relevant notes at the end of the chapter. Blue words in GCR are cases where our definition does not differ substantially from the author's; we keep the blue highlight so that you know that this a word above the target vocabulary level that you're expected to have to look up, but we don't provide the definition if it doesn't add anything.
