Usage
What does ago mean? Ago means in the past. It’s always used in combination with other words that indicate exactly or about how much time has passed since something happened—never by itself (you wouldn’t say That happened ago). Examples of such phrases are three weeks ago, an hour ago, five days ago, long ago, and a long time ago. Example: A long time ago in a galaxy far, far away ….
Etymology
Origin of ago
before 1000; Middle English ago ( n ), Old English āgān, past participle of āgān to go by, pass, equivalent to ā- a- 3 + gān to go 1
Explanation
Use ago to mean "earlier" or "in the past." Dinosaurs lived a long time ago. The adverb ago refers to a time before the present moment, sometimes in the distant past, and sometimes more recently: "She just left for her appointment ten minutes ago." When you talk about the more remote past, you might say "long ago" or "a long time ago." Ago was originally a shortened form of agone in Middle English, "departed or passed away."
