Riddle me this:
There should be two, but instead there is three.
I am connected to the concept of you and me.
My first can be left to the right, conspicuously;
It perceives outness as a sense of depravity.
My second is far from an erroneous place;
It is true and is tried to be won in a court case.
My third dictates construction, but does not have a hammer;
It perhaps also rhymes a little bit better.
Supposedly, the first and the second are attached.
Can you guess what I am; can the details be matched?
I made up this riddle for fun. Hope you enjoy!
Hints for the answer are below.
The first is the shortest with just letters of two,
But the others each have at least two pairs like a barbecue.
The answer is three words that of which are all nouns,
Though one is also a preposition, so that bears the crown.
But it should not be; rather, it should be a prefix.
The grammar is incorrect — this detail is specific.
The answer can be found in one of these hints.
Find it and you might at first think it is a misprint.
Though you must first rearrange to have three and not four.
They say, "Grammar is something you must not ignore."
But how is that relevant to this very riddle?
Well, grammar rhymes with hammer — it is quite that simple.
