Q. How do you pluralize an acronym where the plural form of the word written out does not use an s? For example, if I have an acronym of ALC that stands for Adorable Little Child and want to make the acronym plural (i.e., Adorable Little Children), do I use the s or leave it out? If I use the s and write the plural acronym as ALCs, I feel like I’m saying Adorable Little Childrens, which is not grammatically correct. Would ALC be used for both the singular and plural?
A. Readers are used to understanding that the plural of an abbreviation is made by adding s to it: ALCs (pronounced \ˈā-ˈel-ˈsēz\). You can overthink these things!
