In the Fold

What is wrong with the following sentence?

Bad Example:
The new technique increases production by six fold.

Actually, there are two things wrong.
1)      Sixfold should be a single word, not two words, not hyphenated (–fold is a joined suffix).
2)      In this sentence, “sixfold” is an adverb that tells “how” production increases, so you don’t need the word “by.”

Corrected Example:
The new technique increases production sixfold.

If you use “sixfold” as an adjective, the sentence would then be:
The new technique results in a sixfold increase in production.

I think that sentence sounds better.  But engineers would probably understand it even better if it read:
The new technique increases production by a factor of six.

Very Interesting Proofreading Tidbit:
I was sitting in my Mama Bear Easy Chair reading Family Circle magazine, and I ran
across the following tip and had to share it with the Peanut Gallery.
“By drinking a cup more coffee than usual, people in a Tufts University study increased their ability to spot grammatical errors.”
So the next time you are proofreading your report prior to handing it to the boss, grab a cup of joe first!

Profound Quotes of the Day:

“Truth never yet fell dead in the streets; it has such affinity with the soul of man, the seed however broadcast will catch somewhere and produce its hundredfold.”

“Wealth and want equally harden the human heart.”

– Theodore Parker, American theologian at Harvard Divinity School, 1810-1860
