Follow these guidelines in forming and using plural words:
For most words, add an “s” to pluralize. This includes figures and years.
Right: the early 1920s
Right: several YMCAs
Right: CPAs, CODs and IOUs
Right: in twos and threes
Right: size 7s
Right: Temperatures will be in the low 20s.
Right: She knows her ABCs.
Right: I gave him five IOUs.
Right: They both have Ph.D.s and M.A.s.
There are a few exceptions, including the plural forms of single letters. Form plurals of the following by adding an "apostrophe and s."
Right: S's, A's and I's
Right: x's and y's
Right: Mind your p’s and q’s.
In general, add an “es” to pluralize words ending in “ch,” “s,” “sh,” “ss,” “x” and “z."
(Monarchs is an exception)
Words ending in “y”: If a “y” is preceded by a consonant or “qu,” change the “y” to an “i” and add “es.” Otherwise, just add an “s.”
Words ending in “o”: If the “O” is preceded by a consonant, most plurals require “es.” One exception to this rule includes “pianos.”
For words ending in "s" that are not proper nouns, use only the apostrophe if the following word begins in "s."
Right: Class' syllabus
Right: Class's work
Wrong: Class's syllabus
Pluralizing compound words
To pluralize compound words that are written solid, add an “s” at the end. For those that involve separate words or words linked by a hyphen, make the most significant word plural.
Right: attorneys general
Right: sergeants major
Right: assistant attorneys general
Add an “es” to most names ending in “es,” “s” or “z.”
Add an “s” to most proper names ending in “y,” even if preceded by a consonant. Exceptions include “Alleghenies” and “Rockies.”
Right: the Duffys
Right: the Kennedys
Right: the two Kansas Citys
For others, just add an “s.”
Right: the Carters
Right: the McCoys
Wrong: the Smith’s
