What is wrong with the following sentence?
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.”
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!
