Well, that's actually what stock means,
or it's at least close: it is a log, a stump, or a tree trunk Stock still dates back to the mid-15th century, when we find it in the Scottish poem Golagros and Gawain: "In stede quhare he lay, Stok still as ane stane." Dickens used it in Barnaby Rudge: "The clock - which was very near run down, and would have stood stock-still in half an hour." Both Dutch and German have their counterparts, stokstil and stockstill, respectively. |

You're talking to computer-literate etymologists here. Did you think we'd let you down? The petabyte, which can also be expressed as one quadrillion bytes, got its name in 1975 when the International Committee of Weights and Measures (CIPM) decreed that 10 to the 15th power be dubbed with the prefix peta- (symbol P) and that 10 to the 18th power be called exa- (symbol E). And the CIPM did not pull these prefixes out of thin air. Peta- is supposedly from penta- "five", because peta represents 1,000 to the 5th power. We'll backtrack and mention that tera- comes from tetra- "four" because, you guessed it, tera- refers to 1,000 to the 4th power. Then we move on to exa-, from hexa- "six", zetta-, from septa- "seven", and yotta-, a variation on octo- "eight". See the table below for the number values that correspond with each of these prefixes:
Things are never quite this simple, however. As digital computers work in binary arithmetic, powers of two have more significance than powers of ten. This meant that 1,024 (the 10th power of 2) was a commonly encountered number and, being so close to 1,000, was informally called "1K". This meaning has passed into general usage as far as computers (but not science generally) is concerned. Accordingly, a megabyte is 1,048,578 bytes, not 1,000,000. See the table below for the exact number of bytes in each group:
So what about mega- and giga-? Mega- comes from Greek megas "great", from the Indo-European *meg- "great", which also gave us magnitude, major, and even maharajah. Giga- also comes from Greek, this time gigas "giant", from which we get gigantic and giant, among others. |

From Mark:
You're not very far off, Mark. A mortgage is etymologically a "dead pledge". Here is a great quotation from Sir Edward Coke, a barrister and, eventually, attorney general, chief justice of the Common Pleas, and chief justice of the King's Bench, all in the early part of the 17th century:
The term first appears in the written record in about 1390, in John Gower's Confessio. We should explain how mort + gage = "dead pledge". Mort is, of course, French for "dead" or "death", and gage derives from Old French guage "something of value, a pledge", and is first recorded in the 14th century. Interestingly, a variant of the Old French word was waige, which gave English wage "pay". The same Teutonic root (*wadj-) that gave English gage and wage also gave us wed "a pledge", hence wedding, when a man pledged himself to his wife. (Yes, it was a Teutonic root, and the Romance languages adopted it.) |

From Todd Haidet:
That's a good question. What do notes of a meeting have to do with time? Well, actually, etymologically they really have nothing to do with time. Instead, it seems that English minutes in this sense comes from French minute "small", the notion being that the rough copy of notes taken in such meetings is "small" or made in small writing, versus more formal works that were written in carefully executed script, or even printed via printing press. The original sense of the word was "rough draft" or "a note or memorandum for preserving memory of current transactions". We first find minute with this meaning in the early 16th century. The meaning "official memorandum" is recorded by 1564. The Indo-European root is *mei- "small", which has also given us mince, diminish, minor and minuscule. Notice the spelling of minuscule. Own up, now... how many of you thought it was mini-scule? This is surely another candidate for the ten most difficult English words to spell. |
