Category:Abbreviations, Acronyms and Initialisms

This category is meant to gather abbreviations (cat,) acronyms (cat) and initialisms (cat) in one place.

Acronyms and initialisms are both types of abbreviations. Acronyms are pronounced as the "word" they spell (e.g. NATO, pronounced nay-toe.) Initialisms are pronounced as the individual letters (e.g. FBI, pronounced eff-bee-eye.) The remaining abbreviations sub-category gets all those that fall into neither category (e.g. NY pronounced as New York, or so pronounced significant other.) Abbreviations such as JPEG (pronounced jay-peg) should be in both category:acronyms and category:initialisms.

The original manual list is at Wiktionary:List of acronyms and abbreviations.
