What Does “Sec” Mean? (Definition & Origin)
Sec is a shorthand abbreviation used in texting and online chats. Its meaning depends on context, but the most common usage is:
- Sec = “Second” (as in a short amount of time)
- Occasionally, in specific contexts, people might use sec as shorthand for “secret”, but this is less common.
Origin
The abbreviation “sec” comes from the English word “second”, a term dating back centuries, and was naturally shortened in texting for speed. With the rise of instant messaging, abbreviations like “sec” became standard for quick communication.
How to Use “Sec” in Texts or Chat
Using sec in your messages is simple. It’s usually employed to indicate that something will happen very shortly.
Examples:
- Texting a friend: “Hold on, I’ll be there in a sec.”
- In gaming chat: “Gimme a sec, respawning now.”
- Work message: “Checking the report, one sec.”
Pro tip: Always use sec in informal contexts. In professional emails or official communications, writing out “second” is more appropriate.
