Just like any other website, Reddit has its own unique acronyms. These are used to communicate specific messages to other users.
ELI5: Explain like I’m 5- This one is pretty self-explanatory. Reddit users use this term to put a concept or idea in very simple terms. This acronym is very common on informational posts in which people are learning new information.
TLDR or TL;DR: Too long; didn’t read- In longer Reddit posts, users will comment “TLDR” at the end of their post to shorten what they wrote. This is basically a warning for other users that read the post. Let’s be honest, it is extremely frustrating to read a long article to not find what you are looking for. Reddit users recognize this problem and help each other out.
NSFW: Not safe for work- Users utilize this acronym to warn other viewers about explicit content that is posted. In this specific case, it is to warn users not to scroll further on these kinds of posts, especially if they are in a setting like their job.
TIL: Today I learned- Users apply this acronym to a Reddit post to express their excitement about a new idea. This is helpful for people that just want to discover new information while they scroll through.
OP: Original poster- OP is the most simple acronym of the bunch. It refers to the person that originally posted specific content. This is to ensure that the original poster gets credit for their ideas.
AMA: Ask me anything- This is another name for a question-and-answer thread. Users post this acronym when they are willing to share details about their life, and most often, their occupation.
