== == A plumb is the weight that is used determine depth, so the verb plumb is the act of determining depth. Here the reference is as an adjective meaning from "bottom to top" full.
I found an usage in Robert W. Service's Spell of the Yukon (1907) . It might not first usage, but it is still worth a read.
I wanted the gold, and I sought it,
I scrabbled and mucked like a slave.
Was it famine or scurvy - I fought it;
I hurled my youth into a grave.
I wanted the gold, and I got it -
Came out with a fortune last fall, -
Yet somehow life's not what I thought it,
And somehow the gold isn't all. No! There's the land. (Have you seen it?)
It's the cussedest land that I know,
From the big, dizzy mountains that screen it
To the deep, deathlike valleys below.
Some say God was tired when He made it;
Some say it's a fine land to shun;
Maybe; but there's some as would trade it
For no land on earth - and I'm one. You come to get rich (damned good reason);
You feel like an exile at first;
You hate it like hell for a season,
And then you are worse than the worst.
It grips you like some kinds of sinning;
It twists you from foe to a friend;
It seems it's been since the beginning;
It seems it will be to the end. I've stood in some mighty-mouthed hollow
That's plumb-full of hush to the brim;
I've watched the big, husky sun wallow
In crimson and gold, and grow dim,
Till the moon set the pearly peaks gleaming,
And the stars tumbled out, neck and crop;
And I've thought that I surely was dreaming,
With the peace o' the world piled on top. The summer - no sweeter was ever;
The sunshiny woods all athrill;
The grayling aleap in the river,
The bighorn asleep on the hill.
The strong life that never knows harness;
The wilds where the caribou call;
The freshness, the freedom, the farness -
O God! how I'm stuck on it all. The winter! the brightness that blinds you,
The white land locked tight as a drum,
The cold fear that follows and finds you,
The silence that bludgeons you dumb.
The snows that are older than history,
The woods where the weird shadows slant;
The stillness, the moonlight, the mystery,
I've bade 'em good-by - but I can't. There's a land where the mountains are nameless,
And the rivers all run God knows where;
There are lives that are erring and aimless,
And deaths that just hang by a hair;
There are hardships that nobody reckons;
There are valleys unpeopled and still;
There's a land - oh, it beckons and beckons,
And I want to go back - and I will. They're making my money diminish;
I'm sick of the taste of champagne.
Thank God! when I'm skinned to a finish
I'll pike to the Yukon again.
I'll fight - and you bet it's no sham-fight;
It's hell! - but I've been there before;
And it's better than this by a damsite -
So me for the Yukon once more. There's gold, and it's haunting and haunting;
It's luring me on as of old;
Yet it isn't the gold that I'm wanting
So much as just finding the gold.
It's the great, big, broad land 'way up yonder,
It's the forests where silence has lease;
It's the beauty that thrills me with wonder,
It's the stillness that fills me with peace. http://www.answers.com/spell+of+the+yukon
As an informal word meaning "utterly" plumb may derive from its formal meaning of "exactly vertical." But the variant spelling "plum" suggests that its origin may lie elsewhere.
"Plumb" refers to a "plumb-bob," a device used to make sure that a building is built straight up-and-down (not leaning). "Plumb straight" means "completely straight." In that way "plumb forgot" came to mean "completely forgot."
The phrase 'come full circle' refers to getting back to the original position or the original state of affairs. The origin of the phrase is unknown, but is used in the Western world.
you spell it plumb
Yes and no. The out-of-plumb wall should be hyphenated while the wall was out of plumb should not.
The full phrase is Hell's bells and buckets of blood. A very old naval expression, origin unknown
As far as the UK is concerned, 'I could not eat another thing, I am plum full." This is in reference to the concept of "plumb", i.e. absolutely vertical. Any deviation from plumb is not absolutely vertical. In this respect, if one is "plumb full" it would imply that that the person is "completely full", with no deviation from the absolute term "full". When you consider a container of fixed volume, it is either full or it is not full so by analogy, "plumb full" would imply that the container (generally the stomach) is full, with no room for any more. Realistically, the term cannot be completely true since the stomach is somewhat elastic so saying you (or something) is "plumb full" is really just a way to emphasize the fullness.
The origin phrase for a heart of gold is grande salchichas
There is no such phrase as "eat you".
This refers to the controls of a steam engine on a ship. "Full steam" means full power, or wide open throttle, and "ahead" means in forward gear.
