What Is The Difference Between Alum And Alumni? (Elaborated)

English might be the only language that serves as a global medium of communication since it is spoken by over 1.5 billion natives and non-natives alike. Being a non-native, you need a proper roadmap that you can follow to master this language. And after sometime you will be fluent enough in its usage like a local speaker.

It is essential to note that spoken English differs from written English. If you speak this language, you don’t need to be a grammar expert. Though, while writing in English, you need to keep an eye on various things; grammar and composition. 

Now, when we communicate in English, the nouns vary for plurality. But, this isn’t true for all languages. 

Several languages, including Japanese, have no concept of plurality in their grammar. So, they have a hard time learning the concepts of singularity and plurality. 

Alum and alumni are two nouns that non-natives have a hard time differentiating. 

Alum is a short form used for an alumnus. An alumnus is a singular form used for male students. Whereas alumni are the plural form of an alumnus. Though, both the nouns are used to refer to former graduates.

“I Am An Alum” VS. “I Am An Alumnus” – The Correct Usage

Both the sentences are grammatically and context-wise correct. However, you can’t use both in similar situations. When you’re a former male graduate, you can specifically say “I am an alumnus.” 

Now, the other sentence “I am an alum” can be used for both males and females. This neutral noun is more common than the other gender-specified noun. You must be wondering about the noun that specifically indicates a woman. When you’re a female student, you can say “I am an alumna.”
