I read that というのは can be abbreviated as とは, is that to say that the meaning of というのは is the same as とは?
However, the website I browsed about というのは mentioned that というのは cannot be abbreviated to とは if it is used as a reminder.
I also could not find any relevant english explanation regarding similarities/differences between both of them (e.g. Are both というのは and とは the same word?)
Could anyone shed some light about this?
