What does the term subsequently mean?

The term "subsequently" means "later on," indicating an action or event that follows another in time. It suggests a sequence where something occurs after a prior action. In contrast, the other choices relate to different concepts of timing. "Immediately" refers to something happening right away without delay, "beforehand" denotes an event that occurs prior to another, and "simultaneously" implies that two events occur at the same time. Therefore, "later on" accurately captures the essence of what "subsequently" means in terms of sequencing events.
