Just thought of a neat little game that can help practice philosophy of small subjects rather than huge posts that everyone here can play. :)

So the aim is to play with the meaning of words with a philosophical approach in order to expand its meaning or understanding, refreshing your understanding/views on words to help give greater context to a topic you may read.
Since the subject matter is small you can use the comments to show your findings.
You can mix variations of the word within the field of study, say approach, approaching, approached.
Since not everyone knows the dictionary meaning of every word in such detail you as a reader to someones comment can check with google to gain context to someone's approach of a word.

ill post mine as an example:
-Insane
This word can be used by a user to describe a person who has no context to the person's perspective of thought, the reason of such perspective difference can range from a mental illness, to a person detailing a topic where the user has lost context to the point they deny its validity.

From the Person's perspective you can account for things like "common sense" or "socially acceptable" to the user as their bias on their views of a person to be insane.
The type of insanity depends on how the user of the word is able to make sense of the person with research or dismiss them entirely if the user is not willing to make sense of that person at all.

In terms of mental illness it can change one perspective by some biological difference but it is still a difference in mental perspective fundamentally.

So with this, the meaning of the word insanity is to describe difference of perspective in mental thought,
rather than what a user may assume to be: "extremely foolish; irrational"
