Making an Abbreviation Plural
Simply add an “s” to an abbreviation to make it plural. (Do not add an apostrophe.) I work with five other RNs during a typical shift.
Are abbreviations singular or plural?
The plural of an abbreviation or acronym is usually formed by adding "s" to the end. For example: MOT > MOTs. ATM > ATMs.
Do you use an apostrophe for plural abbreviations?
When something belongs to multiple items or acronyms (plural), you add an apostrophe to the plural word of the acronym. For example: There are five UFOs over there. The UFOs' lights are different colours.
