The plural of memorandum is memoranda or memorandums.
A memorandum, often shortened to "memo," is a written message or communication that is typically used in a business or government setting.
Memos are used to convey important information, instructions, or requests to colleagues, employees, or other individuals.
So, what is the correct plural form of memorandum? Both "memoranda" and "memorandums" are technically correct.
"Memoranda" is the Latin plural form of the word, while "memorandums" is the anglicized plural.
While both forms are considered acceptable, "memoranda" is considered the more traditional and formal option. This version follows the standard rules for forming the plural of Latin words ending in -um by replacing -um with -a.

"Memorandum" is a singular noun, meaning it refers to one specific written communication. It is important to remember that even though memoranda may contain multiple messages or communications, it still refers to one singular entity.
When using the word "memoranda" in a sentence, it is important to use the correct verb agreement. As "memoranda" is a plural noun, it requires a plural verb.
For example, you would say "the memoranda are being published" instead of "the memoranda is being published" because you are referring to multiple written communications.
A countable noun is a noun that can be counted, and memorandums are countable because they can be counted or quantified as individual items.
For example, if a company produces several memorandums, you can count how many there are, and they can be individually referred to as "one memorandum" or "two memorandums", and so on.
Moreover, when a noun is countable, it can be used with both singular and plural forms, depending on the context of the sentence. For instance, "I received a memorandum" refers to a single memo, whereas "I received several memoranda" indicates the receipt of multiple memos.
