Apostrophe Before Suffix for Verb Forms

The Apostrophe

Rulebase Summary

Use an apostrophe before adding a suffix to show that a letter, number, or abbreviation has become a verb form. When a shortened word that ends in c becomes a verb, add k to preserve the hard sound before the suffix. Consult a dictionary to see which words follow which patterns.

A. He OK'd the purchase order that morning.

An apostrophe is used before the suffix when an abbreviation becomes a verb form.

Use an apostrophe before the suffix to show the abbreviation is functioning as a verb.

Transcript Notes

Words like emceeing and deejaying are replacing the older abbreviation-plus-apostrophe forms (DJ'ing, MC'd). Dictionaries also use the hyphen before adding a suffix to show that a letter or abbreviation has become a verb form (bs-ing, od-ing, x-ing).
