How it's used
Reserved primarily for formal contexts like academic texts, philosophical discussions, or technical jargon. It carries a sense of intellectual weight that makes it sound unnatural if used to describe everyday tasks or simple chores. When describing something that is just physically hard to do, use 難 instead.
Examples
The content of this book is too abstruse, I can't understand it.
Do you have a simpler way to explain it? This one is too complex.
Related words
Common phrases

Common mistake
Learners often confuse this with 複雜, which refers to something having many intricate parts or layers. 艱深 specifically highlights the difficulty of comprehension or the depth of the subject matter, rather than the complexity of a structure or process.
