What does a tenfold increase or increase tenfold mean?
Does the suffix “-fold” refer to powers or multiples?
Explanation by Elisa English
The suffix "-fold" refers to multiples. Tenfold means ten times as much. There is no such usage as onefold.
tenfold = by ten times, ten times as great or as much
The sales is currently $2 billion. We expect it to increase (up to) tenfold in 2011. In 2011, we expect the sales to be $20 billion.
