Apostrophe or Hyphen

Margie Wakeman Wells General, The Apostrophe, The Hyphen Leave a Comment

When there is a quantity, measurement, distance, value, amount that is expressed as a direct adjective (right in front of a noun) AND there is an “s” on the adjective, use an apostrophe “s” when it is singular and an “s” apostrophe when it is plural.

…one minute’s delay
…five minutes’ delay

…one week’s vacation
…two weeks’ vacation

When there is no “s,” use a hyphen.

…one-week vacation
…five-minute delay

When there is an adjective rather than a noun after the combination, there is no apostrophe or hyphen.

…seven months pregnant
…one month long

Happy punctuating!
