**Initialisms**

Initialisms are abbreviations formed from the first letters of a series of words, pronounced letter by letter rather than as a single word. Common examples include FBI (Federal Bureau of Investigation), ATM (Automated Teller Machine), and CPU (Central Processing Unit). In language and writing, initialisms serve as concise, efficient ways to reference complex terms or organizations without repeating lengthy names.
