# OK "lack of knowledge" vs "unclarity"

What if you are seeing an interesting (or not) question and want to answer it, and if you can't understand something in the post, because you don't know it, for an example consider a question regarding hybridization (like $\rm sp^3d^2$) and you don't know what is d (orbital). In that case would you down-vote it as "unclear" or try to study that either on internet or in your course or waiting for it to be taught to you until the time comes? Your opinions.

• I think that it is fine to seek clarification in comments, as @Martin did here to one of your questions. That's one of the purposes of comments (your comment after was not very constructive tbh).
