  3. This book is the first volume and part of the ten year period of..

Which is correct?

Answer

Number (1) is correct. When a hyphen is used to join two words, they become one “thing” together as a whole. E.g.

  • A ten-year period
  • Two ten-year periods
  • A multimillion-dollar machine

Note that the “A” is referring to the number of objects being described, i.e. “period” and “machine”. “Ten-year” is an adjective for “period”, and “multimillion-dollar” is an adjective for “machine”.
