User blog:EmperorZelos/Language and Logic

Logic is such a common word used these days to properly deduce things from one or more premises. There are certain rules to it and more but I will go through a few and how they can be applied for language and distinctions in it, or lack of them. For easyness I will be using a table like where A and B represent the two options possed and X will be replaced by the function. If it shows 1 in the box it means that option is applied in that situation and 0 means it isnt.

Or
This is a common word and logical function, It usually represent where A can be the option or B can be, but also both can be valid at once. This is the commonly spoken "Or" but may be emphezised by saying "A or B or both" in everyday speech to make it clear compared to the other or. This is in technical terms called "Inclusive Or" but will in this blog be refered to simply as "Or" as the other got another name in short terms.


 * Or: Him or me or both

Xor
Xor is the other kind of or, it represents a kind of or where the option of both being valid/true is excluded, hence Called "Exlusive Or" or simply "Xor" There are languages, including my own, which makes this distinction of when the option of both being valid makes the words change. Many langauges do make this differens but uses expressions for it including english.


 * Or: Him or me or both
 * Xor: Either him or me

And
And is among the most used and general words in english again, in logic it means that A and B must both be true at the same time

This holds true in normal language aswell as the two being tied togather always share the thing in question that is being talked about.


 * Or: Him or me or both
 * Xor: Either him or me
 * And: Him and me

Xand
This one is more used in Logic than in languages as far as I know, but it is like and with the differens that both can also be held false aswell, either both are true or both are false in the form of "Either he and I did it or neither did" which could be formex as "He xand I did it"


 * Or: Him or me or both
 * Xor: Either him or me
 * And: Him and me
 * Xand: Him and me or neither

Adj-and
This one is considerbly less about logic in traditional form but more a linguistical differens in meaning. Think on the sentence "The red and green man walked".

It can mean one of two things, either a man that is red and green coloured at the same time walked, or a Red coloured man and a green coloured man both at once walked. How is that differens known? Usually in english by context but languages can make the differens by a different conjunction. For simplicity I call it Adj-and.
 * Or: Him or me or both
 * Xor: Either him or me
 * And: Him and me
 * Xand: Him and me or neither
 * Adj-and: Green man and red man

More to come, all for now, suggestions thoughts are welcome
