Just has become a mere placeholder in daily language. "I'll just put it over here." "That's just about right." "I heard it just now." "Just in case." It's said so often that we don't really know what we are really saying when we say it.
The dictionary defines Just: guided by truth, reason, justice, and fairness. It actually comes from the Latin word justus righteous, equivalent to jus law, right.
So what are we really saying when we say, "I'll just put it over here."? Are we saying that it's fair or righteous that we put it over here? When we say, "That's just about right.", are we saying that just is almost right or that right is almost just?
I like the sound and the implications of the word Just. It is complete, especially when you know what the word means.
Just so you know, it's not just a filler-word to me. It's an answer that begs no questions, a statement that covers all.
