Its been awhile since I spewed forth any thoughts on English, so its a good time to catch up. This concerns the proper usage of "This Here" and "That There". People, especially those who don't use these terms often, have been known to get them confused.
"This here" is loosely translated as "This", while "That there" is loosely translated as "that".
When someone says "This here", they should be referring to an object close by, maybe even something they're holding in their hand.
When someone talks about "That there", they should be referring to an object at a somewhat greater distance away, anywhere from a few feet away to something way over yonder. Or maybe something that's not even present.
Also, "This here" is frequently pronounced "This 'ere", and "That there" is frequently pronounced "That air", so don't get confused. No one's talking about ears or atmosphere.
1. I'm fixinta wallup you with this 'ere stick!
2. That air dog's dummer 'an river mud.
You really will only get the hang of the correct usage thru practice, so try it out!
