Abbreviation, Initialism and Acronym lec#28 for CSS PMS and other competitive exams by Qaisar khan

An abbreviation is a general, broad term for any shortened form of a word or phrase. Both initialisms and acronyms are specific types of abbreviations. • Abbreviation: A shortened form of a single word or phrase (for example, "Prof." for professor or "Jan." for January). • Initialism: An abbreviation formed from the first letters of a group of words, where each individual letter is pronounced separately (for example, FBI, ATM, or BBC). • Acronym: An abbreviation formed from the first letters of a group of words, where the combination is pronounced as a single word (for example, NATO, SCUBA, or NASA).
