Hyphenation Exercise (135)

Revise the sentences to correct any errors of hyphenation, removing unnecessary hyphens and adding any that are missing.

Answers and Explanations

1.
Original: After the long grueling hike, we were all-in.
Correct : After the long grueling hike, we were all in.

The phrase "all in" means exhausted. It is not hyphenated.

2.
Original: I just discovered that my great-grand-mother gave birth to fourteen children.
Correct : I just discovered that my great-grandmother had fourteen children.

Compounds with grand are closed. Compounds with great are hyphenated.

3.
Original: Our department has been accident-free for 273 days.
Correct : Our department has been accident-free for 273 days.

Compounds with free are always hyphenated, both before and after the noun. The sentence was correct.

4.
Original: We succeeded because everyone in the department made an all out effort.
Correct : We succeeded because everyone in the department made an all-out effort.

As an adjective in front of a noun, "all-out" is hyphenated.

5.
Original: We have experienced a 5 percent increase in sales since this time last year.
Correct : We have experienced a 5 percent increase in sales since this time last year.

The sentence was correct. Compounds with "percent" are never hyphenated.
