What does the word "WhatsApp" mean - in detail?

The term "WhatsApp" is a portmanteau of two words: "what" and "app". It was coined by Jan Koum, one of the founders of the messaging application, in 2009. The name reflects the original purpose of the app, which was to allow users to check the status of their friends online, similar to how they would ask "What's up?" in casual conversation. Over time, WhatsApp evolved from a simple status-checking tool into a full-fledged messaging platform that supports text messages, voice and video calls, and multimedia sharing. Today, it is one of the most widely used communication tools worldwide, with over 2 billion users across more than 180 countries. The name "WhatsApp" has become synonymous with instant messaging and has left a significant mark on modern digital communication.
