Other forms: futures; futurely
A time that hasn’t happened yet is the future. You're reading this in the present, and what you read by clicking on the link for the next screen will happen in the future, i.e., in the time ahead.
Future goes back to the Latin root futūrus "about to be," and it is a noun or an adjective referring to things to come. When we hope, we are often imagining what will happen in the future. You might dream of becoming a doctor in the future, or you're looking forward to the weekend, just days away but still in the future. Now is the present, yesterday is the past, and tomorrow is the future, the opposite of the past.
